Replying to 24 Weeks of woodworking class to make whatever!

Posted this in Build a Jib 101 but its sadly dead : (

Hey guys for the next 24 weeks of class I get to work on whatever it is I want. I'm able to make multiple projects or just one big one. I already have a summer setup, and a couple rails. I was thinking maybe a portable drop in for winter or something a bit more creative.

So.. Do you guys have any ideas on what I could/should make. (24 weeks worth of time to make something) +k for good ideas
