Perspective #default #shadow

u/Agnes

It's a shame all of these x.reset() dweets don't work on iOS... :(
u/rodrigo.siqueira

...thanks for letting me know about this iOS limitation. So, I’ll stop using x.reset and go back to using c.width instead.
u/0x61

Should be noted reset is working fine in iOS 18.1
u/magna

Dwitter could also monkey-patch 2d context to get x.reset() working

Explorations through unknown structures

u/vain

Wow, brilliant. With a little imagination you can recognize a skull face. Did the formula come about by chance or is it based on some known algorithm?
u/rodrigo.siqueira

u/vain , you can click 'remix of...' enough times to see where the formula comes from. It originates from Saturn by u/tomxor
u/rodrigo.siqueira

(t*i/b&1) could be shortened to (i*b&1) and it is a random binary number "0" or "1". The variables a and b evolve over time in a discrete dynamical system, producing oscillatory, chaotic, and fractal-like behavior.
