Challenge Me.

I want someone to give me a challenge. Something to build that revolves around redstone. I will give myself one hour to complete it, should I choose to do so, and the result will be posted on PMC in Projects with your PMC or Minecraft name in the Additional Credit box. Here is the Application/Challenge forum:
