Had a great time on the What the Tech podcast back at my old computer science department! We got into app development, science, education, and AI. Thanks for having me Enisha and Hareem. Check out their other interviews, so well done. open.spotify.com/episode/3zAu...

Vibecoding with Claude Code ✨

Yay! I can't wait to meet so many amazing developers in June, especially the visionOS community 😀

WIP: Trying to do something more interesting with the disordered regions of synaptophysin (green) in the syp-vamp2 complex of this synaptic vesicle. I have this bug at the moment, a little nightmarish, but cool looking. Flailing tentacles...

WIP: modelled the synaptophysin-VAMP2 complex for our synaptic vesicle. This complex is involved in vesicle fusion. SYP forms a hexamer with 12 copies of VAMP2, a key part of the fusion machinery.

Lazy morning building a synaptic vesicle from scratch. Super WIP and not correct. Much to do. But it has the coolest guys imho: - Amber: Vesicular glutamate transporter (VGluT) - Red: V-ATPase No membrane. Need VAMP complex, etc. #screenshotsunday

WIP: Updated CellWalk's editor for macOS. I love how liquid glass adapts to the scene's colour palette. We're looking at an HIV model the folks at Scripps Research (this is just our dev tool)

@dreamwieber.bsky.social just released a beautiful video exploring my app CellWalk on the M5 Apple Vision Pro. Totally made my day. Thanks for the support Gregory! :)

I just updated CellWalk for the M5 Apple Vision Pro! This app really pushes the GPU (entire cells with billions of atoms) and it's a great way to test the M5. CellWalk on M5 increases resolution and detail 1.5x over M2! Huge. It's super sharp and detailed. Apple Intelligence is also way faster.

I quietly released new features for Apple Vision Pro in the last update: Widgets and on-device AI explanations powered by Apple Intelligence. I don't have an M5 yet, has anyone tried CellWalk on the M5 Apple Vision Pro?! How is it? more resolution (it should get more by default)?!

CellWalk is featured in Apple's new article on Apple Intelligence and Foundation Models. It's a really fun new way to learn about concepts and terms in the app, and I really enjoyed building it.

Getting ready for my talk tomorrow on "Thoughtful Spatial Design" at KWDC25 tomorrow! Hanging out at Fritz Coffee in Gangnam, Seoul. I love this location, nostalgic vibe.

🦠 NEW VIDEO 🦠 The molecular biology of how Mycobacterium Tuberculosis evades the immune system so well. Starting with this simulation of a full outer envelope of m.TB--let's explore how the deadliest & most persistent human pathogen completely hacks our immune response. #molecularbiology

Check it out! The @ucalgary.bsky.social where I did my PhD just published an article about my app, @cellwalk.bsky.social being a Finalist in the 2025 Apple Design Awards. Super cool. www.ucalgary.ca/news/ucalgar... #wwdc25

Check it out! I'm proud to unveil CellWalk 2 for Apple Vision Pro. Bring beautiful and immersive biology learning into your space. @cellwalk.bsky.social 🧬🦠🍎 #science #applevisionpro #visionos #apple #wwdc25

Ahh!! My app CellWalk is a finalist in this year's Apple Design Awards. What?! 😮 I'm beyond excited. Thank you Apple for the honor, and a huge thank you to the incredible people there. #wwdc25 @cellwalk.bsky.social

I need to store a fair amount of data alongside my Git repository hosted on GitHub. I've been pricing things out: GitHub LFS: $70/TB LFS Cloudflare R2 + Webworker proxy: $15/TB LFS Backblaze B2 + Cloudflare Webwork: $6/TB I went with Cloudflare R2 for Git LFS and GitHub for the repo!

OpenAI’s new GPT-4o image generator is kind of mind-blowing, especially compared to what was state-of-the-art just days ago. Someone had to try the Ghibli trend on some crazy biology visuals, right? Here's my beloved whole cell model in Studio Ghibli, graffiti, cubism, abstract, and pop art style ✨

Christmas in June! I hope I can make it to this one and meet some of you. What's on your wishlist for visionOS 3? I'm personally hoping for big upgrades to CompositorServices and the ability to directly prompt Apple Intelligence. developer.apple.com/wwdc25/?cid=...

What a nice sight to wake up to 😊🌀 The amazing work of @cellarchlab.com, @florentwaltz.bsky.social and their team made it on the cover of @science.org and I had the honor to create the visuals! I hope you like this ATP (animated title page 😉 you see what I did there?).

We're on the cover of @science.org this week. Awesome work by @florentwaltz.bsky.social. #CryoET is reaching crazy resolutions inside cells, and this is just the beginning. Fantastic interpretation of the proton motive force by @verenaresch.bsky.social. Always a pleasure making #SciArt with you!🧪🧶🧬🌾

Wow, my first #bluesky post, let's go 🚀-- I'm excited to share I have been invited to #ComSciConHouston on April 12, joining Daniel Whiteson for a panel on Science Communication through Different Mediums! lnkd.in/gXwUzWmR

Super appreciate being featured on spatial-apps.com by @spatiallyme.bsky.social ! Thanks for giving it a shot and placing it among other great apps for Apple Vision Pro 😀🥳

I was honoured to guest lecture on visionOS development and CellWalk at the University of Calgary’s iOS Programming Course. Also got to check out some promising student projects—definitely some Y Combinator potential in the mix!

Holy smokes, this is a really good animation. The side-by-side presentation gives a really good picture of what's happening locally and globally. I just watched this 15 times. Wow @margotriggi.bsky.social and the @briggsgroup.bsky.social

Great intro to the Apple event today on Immersive Storytelling for Apple Vision Pro by @settern.bsky.social – I'm gonna start this thread for any other Bluesky Vision Pro / XR peeps who want to share related stuff. Reply below! ✨

Happy to announce, my 2nd solo app ever Silk Road Journey has launched on #VisionPro. It leveraged great capabilities of VP & transform tech into history alive. Bringing important cities to you, just like being there. One millennium, just one touch away. #travel #apple #indie #buildinpublic

👋 from the Swift team, now on Bluesky!

Working on @cellwalk.bsky.social in a beautiful location

The Apple Vision Pro was released one year ago on this day. Like many developers, the lead up to the Apple Vision Pro launch was a blur of development. February 2nd felt like a global celebration of something extraordinary. Congratulations to the teams at Apple for creating something truly magical!

I need your help! I'm doing my first user study (ahhh!!), and I'm looking for a few awesome users to interview. If you have used my app CellWalk (any platform), would you be willing to hop on a zoom call with me for about 20-30 minutes?! I would love to buy you lunch (via PayPal). 🧪 #EduSky

I finally finished a new optimization for CW's render tech on Apple Vision Pro (profiling on an M2 iPad GPU). Super happy because it took a few weeks to implement. This is the Terarosa POSCO branch (Seoul). Super beautiful place to work

Anyone remember Earth: 2025?

Happy New Year from Seoul Far from home, I've been reflecting on the years developing CW. Even though the video starts with 2020, the journey began 12 years ago. It will take many more years to achieve the full vision, but in this moment I'm grateful for where we are.

More screenshots. CellWalk's new ambient occlusion technique (right) vs the old one (left). #AppleVisionPro These are render targets captures. 8spp (old) vs 48spp (new) 1.2ms (old) vs 400us (new) The new technique is super optimized. Loses final detail though.

CellWalk's new ambient occlusion and noise filters. 48 samples/pixel. About ~300-400us for the ao kernel in this scene. Taken on #AppleVisionPro Still a few more artifacts to fix, but it looks so *good* now, and it's 2-3x faster than before (and 6x more samples) #graphics #computergraphics #sciart

Announced: The PDB Molecule of the Month for December is the flagellar motor! An informative article paired with a beautiful artwork by Dr. David Goodsell. pdb101.rcsb.org/motm/300 @rcsbpdb.bsky.social #Science #Discovery #PDB This is my favorite Molecule of the Month!

A quick molecule of the month render for November's Malaria Parasite PTEX (pdb101.rcsb.org/motm/299) using #b3d and #MolecularNodes #GeometryNodes #SciArt

Sebastian is one of my favorite graphics engineers to follow because he's optimizing and developing for mobile GPUs. I've learned so much about optimization and GPU architecture from his posts on Twitter. It's made CellWalk faster and more efficient. Give him a follow! He's awesome.

Happy Holliday Junction for those who celebrate

🧵Okay a thread of every Apple Community Starter Pack I could find! I'll keep updating as I find 'em because why is this so hard to search for 😭???

This week I focused on CellWalk's lighting on #visionOS (CompositorServices + Metal). Before (very noisy) vs after. I'm really happy with this result, but there is still so much to implement and improve.

Hello Bluesky! I'm looking forward to seeing lots of #sciart and #science in my feed again! 👋
