Reverse engineering IR remotes, and implementing them into my own projects has been an interest of mine for the past few embedded projects I worked on at home. The hardware overhead for getting a wireless IR transceiver working is basically nothing, and there's something especially pleasing about requiring line-of-sight for accurate transmission. The novelty of line-of-sight works especially well for game-based projects!
