Heavy, and I didnt go for the true logo ;) but maybe it gives some ideas..

u/lewdev

I've never seen setLineDash before. Interesting.
u/Agnes

Why would they give us fillText and strokeText but not just text so we can add it to the path and do interesting stuff with it :(
u/cantelope

u/Agnes because like any path function, there are 2 ways to complete it, fill or stroke. text is just polygons
