64 pixel RGB LED Display - Another Arduino Clone

It has been done, but it comes at a cost.

Generating the PWM in software for true-color (sort of) takes up a big slice of CPU time. At some point, there's nothing left for anything else. If I had to do it again for a 128px display, I'd at least use dedicated LED-drivers with integrated PWM generation. A faster micro would help as well.

How about combining 2 of these, for like a game of tetris or just a larger game/screen is is possible to just hook up more ic`s and a second screen ?
