Smooth!
u/New_Core

Would be nice if dwitter had so you could post an example based on a dwitt without posting a new one. for example on this one I would post.. c.width=2e3;for(y=1500;y--;)a=y%29,b=y%52,x.fillRect(b*40,a*40,C((b*a)/8+t*2.5)*40,S((b-a)/7+t*3)*40)
u/iverjo

Ah, a golfed version :)
u/lionleaf

Good idea, I've been toying with the thought for a while. What's your take on how it should look / work in practice? Allow comments to be a dweet that can be opened and closed?
u/New_Core

one way would be to have like a offspring dweet button... when you use it the code will be placed in a dropdown list under the original dweet.. not sure how it should look like but the original show allways first and then you can select an edited version. (keeps comments clean)
