I do these things called tweetcarts all the time. Basically you have to fit all the code you use to make something cool within a tweet (using pico8 which is a fantasy console). This is probably one of my favorite ones I've done, here's the code:

--#tweetjam

s,t,r,m,u,v=sin,0,8,rectfill,.32,1/32

::_::t+=.01cls(1)

m(33,0,94,127,12)

for i=0,32 do

for j=0,r do

y,z=-t+1/r*j,i+1

m(64-i*.2+s(v*i*u+y)*32,(i*u)^2,64+i*.2+s(v*z*u+y)*32,(z*u)^2,7)end

a=s(t*8+i*.03)*4

m(i*4,109+a,z*4,127,7)

m(i*4,116+a,z*4,127,12)end

flip()goto _
