For my final project in my digital electronics class, I am building an 8x8 LED matrix on perf board and hooking it to a breadboard which is powered by a breadboard companion. I have to make it display 3 different images. I have realized, however, that it is going to get pretty messy. I saw something here where he connected the grounds of the columns and anodes of the rows so that he could control each individual LED that way, then he made his circuit do this fast enough so that you couldn't tell that they were blinking. I have a very basic/limited variety of chips that are accesible (7-seg.s, AND, OR, NOT, R-pack, NAND, PLD's, etc. Basics...), and I was wondering, what would be some various ways to go about building a controller that would be able to display an image?
