> Flipping something over like that looks cool, but confuses the brain. At least it confused mine. I think it would be helpful to have a shadow of the right matrix after it's moved to the top. This way it would be easier to see where particular numbers are coming from in the original input. Disclaimer: I'm similarly biased and actually the reason I came up with this shadow thing is because I also imagine the right matrix moving like here but somehow this never causes it to disappear from its original place on paper, go figure, so this animation looked really alien to me.
