Nice way to draw arcs in the screen (by Tracy)
there is draw_arc function in that last otto code. This one can handle different shape curve via that height var, but you could fix that h value. Calc is at (0,0), then code shifts it to where it needs to be. I believe it uses:
I wrote some code with large shadowed scrolling font TokyMaker, the letter o,a,e all have curves in them, this one also walks though x solving for y but uses Pythagoras formula a^2+b^2=c^2. Also in a function called draw_arc, but only coded for being round. No shift on this one, just draws where it is needed directly. code is much cleaner and easier to read.
Both codes have a draw_arc function but coded differently. If you add something into otto_v2 as a function, a mode value could use it, then you get menus without needing to code them.
Finally I added a very simple version of ottoky eye expressions.
