  • Somewhat ambiguous because of implicit orthographic projection

    Welcome! Very nice 1st Dweet! Golfed to 131b -> c.width=w=400; with(x)getImageData(fillText(font="17px Hello",0,19),0,w,j=99).data.map((e,i)=>e&&fillRect(j*C(i%w/63-t)+j,i/w,3,3))

    thanks for the nice comments ! u/jylikangas cool tricks but it seems like inlining fillText in getImageData won't work in FF :(
