u/BackendForth

Nice!
u/magna

Nice! The z is inverted for me...
u/tomxor

Neat. Magna, are you uncrossing your eyes by any chance? :P (i.e making your eyes further apart)
u/magna

u/tomxor yeah! I've gotten used to relaxing my eyes and looking "afar", from the way SIRDS normally work. I don't I can cross my eyes without looking at something actually close to my eyes. I suspect most people are more comfortable with relaxing their eyes than crossing them...
u/smtsjhr

so fun!
u/joeytwiddle

If you are a person like magna, change: fillRect(w to fillRect(3*w and +w*j to -w*j
