For Pi Day (3/14) of 2019, I decided to create a tweetcart showcasing the Monte Carlo method of approximating pi. This method calculates the distance between the origin and a random point from (-r,-r) to (r,r), where r is the radius (in this case, 1). Then, the total number of dots within the circle (or, […]

One of my favorite tweetcarts. Showcased in the Museum of Tweetcart History. A tweetcart is a Lua script that can run in Pico-8 and fit within a single Tweet, with 280 characters or fewer. s=sin c=cos l=line::_::cls(7)u=t()/4q=.7+s(u)/9p=.75+s(u+.2)/9i=64+16*c(p)j=32*s(p)for z=1,5 do d=u+z/5m=8*c(d)*c(q+.3)n=8*s(d)*s(q+.3)x=i+m+4*c(q)y=j+n+4*s(q)e=q-s(d+u)/30l(i,j,i+m,j+n,2)l(i,j,64,-8)for w=x-2,x+2 do h=y+(x-w)*c(e)l(w,h,w+64*c(e),h+64*s(e))end end flip()goto _
