This is very cool. I suspect the author encountered that 12 pixel offset due to a default value on the canvas’s text baseline property. Setting this to `top` may resolve the issue, or invoking the `measureText` method and calculating the offset from the output. A fixed value for a monospace font is pretty good too!

Shameless plug, I’ve actually built the opposite of what the author has described. Asciify[1] is my very own highly efficient and over-engineered tool to generate animated text art. It started as an excuse to learn more about browser performance and just expanded out from there. I would love it if a greater mind could squeeze another 5 or 10 FPS on the spiral demo[2]. Maybe it’s time to brush up on those WebGL docs again…
