I was very bored recently, so I decided to build this thing, it uses a lot of different systems to get a redstone signal to a wool G, which then burns down in a shower of XP orbs! This project took about 3 days to finish, but it works like a charm! have fun, and you can use anything in the map wherever you like, the only original idea was the system for the pistons and redstone lamps, anyway, hope you enjoy my little contraption, GoldGamer
