I liked the Idea of Etho's trivia game on Mindcrack server and tried to build my own version without pistons.

I have prepared 10 easy Redstone-related questions, so give it a shot and tell me how much did you get!

The system was built in 13w10a, and I checked it in 10b and 1.5pre-release. The reset button might need few punches in the 10b and pre-release, because of buggy droppers in the snapshot. The later snapshots might break something else, so I'll make a tutorial after the stable 1.5 release.
