Did you HAVE to use stuff like ⵠ as variables?

u/Xen

nice!
u/mxfh

Yes I do anyway. What’s not to like about it? See https://www.dwitter.net/d/855 anyway. Find it most descriptive in the context of the limitations of dwitter. Btw this just done fudging and pasting around in iOS Safari when I can’t fall asleep. Just did feel like posting this one.

Not sure why and how... but it looks to me like a rotating head with human body... amazing. Maybe this would look cool with transparent/blending drawing
u/tomxor

Interesting pointcloud encoding. Looks like each codepoint's index is Y, and it's value is both the angle in radians and distance from center.
u/neimad

Looks like meditating buddha

Meditating Buddha, yes!

u/joeytwiddle

Almost tomzor. The index is Y and also the angle, hence the spiral visible in remixes. p0i used that index for his globe in d/5600
