The chart I'm using is "X Y (Scatter)" sub-option "Scatter with Straight Lines." I always try to create an adaptive pattern that can change with different settings. I can graph a lot of separate lines in a series entry by using VBA to turn off the line format for every data point between lines.

I decided on creating two different colored forests. #ApollonianGasket #art #cartography #fantasy #MathArt

I created many pages of inked mountains and forest parts and scanned them in to assemble into my fantasy maps. Eventually I may create more traditionally shaped maps, but I find making them into Apollonian gaskets the most interesting. #art #cartography #fantasy #worldbuilding

Here is the beginning of a fantasy map I worked on recently using an Apollonian gasket as a base. Digital effects and coloring done in Krita. #art #fantasy #cartography #MathArt #worldbuilding

An Apollonian gasket I created using Excel for a fantasy map template.

I've long been fascinated by Apollonian gaskets. Being able to create them using Excel opened up the creative possibilities for unique knots, chain patterns, robot eyes, and fantasy maps. #MathArt

Alien heads concept art.

Got in some digital painting. After half a lifetime using the same signature I think I've settled on this new simplified one using impact font. #art #ConceptArt #Creature #DigitalArt #fantasy

I've been ink drawing fantasy heads. I wonder where the line is drawn between an elf or fae and an alien or monster? I imagine a taxonomical continuum where there is some overlap in features. #SeelieCourt #Sidhe

I've been using my Excel and Krita skills to create components for later illustrations. This is a small sample featuring robot parts. I'm trying to achieve something towards Kevin Long's technical brilliance in art. His work in Rifts RPG has fascinated me since its inception.

Been trying to do some Kevin Long style art. Inked drawing shaded with textures made in Excel and applied in Krita. #Rifts #robot #rpg #scifi #ttrpg
