If you're going to demo something (like 3D graphics in React Native), better make it as creepy as possible

Rendering 3D objects on three platforms (web,ios,android) with single code base using Expo and react-three-fiber:

Testing out Lynx. Coolest thing so far is styling with normal CSS, and things like gradients and box-shadows just working without platform specific syntax changes.

My summer home is almost finished but I think it's safe to say that it turned out pretty nice

Made a few small edits, also working on a Play store specific section
