[paint editor] use the keyboard to change the paint and use your mouse to draw

You can hijack a global that you don't use like S, C or T instead of E to avoid that initial "ReferenceError: E is not defined" error.

Spikey circle

u/BirdsTweetCodersDweet

if you add t=0 at the very start, and kkep typing +.1, you can step through and see all the cool patterns it makes along the way :D
u/BirdsTweetCodersDweet

Kinda reminds me of the old days of logo programming as well :P
u/trancor

That little turtle was great! Good looks! I added t=~(t*4)*.1; 4 is the slide show rate, .1 the steps.

Nice!

Remixed from @micahcowan's https://www.dwitter.net/d/8781

u/davidsharp

swap .7 for speed, for crazy things like:with(x)for(i=n=90;--i;)F=(f,m)=>Math.abs(m-t*.4*f(i*1.5/n)*2e3%(2*m)),font='90px a',fillText('🌚🌝🍀'.substr((i%3)*2,2),F(C,1920),F(S,1e3))
u/micahcowan

Using u/magna's [...font] trick in d/8783, and removing an extra invisible character that appears in the list of balls (VARIATION SELECTOR - its absence may change the ball look for some people? didn't for me), it became possible to restore the screen-clearing. with(x)for(c.width|=i=n=23;--i;)F=(f,m)=>Math.abs(m-t*.7*f(i*1.5/n)*2e3%(2*m)),fillText([...font='90px ⚽🏀🏈'][5+i%3],F(C,1920),F(S,1e3))

That's a really neat trick 👌
