LFSRs were used in game development for many years as "random" number generators that were guaranteed to always produce a series of "random" numbers that returned every value within a range precisely once. It was a way to save memory when you didn't have enough RAM to store the entire list of randomized numbers. It was also used in level generation, e.g. Pitfall, and other games. I used an LFSR in a couple of games for word generation and level layout, which was especially important when you only had 6KB of storage total.

Also good for those full screen fizzle fade-ins.
