That's great, but the question of the decade is still what finger to use on the spacebar.

P.S. Looks like it's also a working memory trainer, since you have to remember which letter chain appeared on the screen first. Still kind of cool.

I had the idea to wait for a few letters so I could type them all at once, but by then, it was too hard to figure out which one had come first (I'd assumed it didn't matter and was just trying left-to-right) before they all reached the bottom and I couldn't catch up.
