Zorbing
My wife and I went to New Zealand back in 2004 and loved it. LOVED IT! I was looking through some old photos and stumbled across this one:
Becky and me Zorbing in Rotorua, NZ
Ah... good times! It makes me want to go again. I just checked out http://www.zorb.com/zorb/locations/ and found that they have a location in the US! We'll need to plan a trip to Tennessee soon. 
If you aren't familiar with Zorbing, the basic idea is that you climb inside a gigantic plastic ball and then roll down a hill. It is a blast.
Newest programming project- Library Queue
A couple months ago I started work on a new personal project: Library Queue. The project is to build a website/webservices that will enable users to manage a queue for checking out movies from their local public library much like a Netflix queue. I'm not sure how other library web sites compare, but at least for the Salt Lake City public library (http://slcpl.org) browsing and searching for movies is not user friendly at all. It really could be soooo much better if they were organized and presented in a UI similar to Netflix or Redbox. And the other aspect is a queue of movies you'd like to watch at some point but don't want to put a "hold" on all the movies right then.
I'm thinking that you will be able to configure the queue system to look at your currently checked out movies and the currently on hold movies and then will only move things from in queue to hold when there is "room" for it. Meaning, if I set a limit to "Number of movies checked out or on hold" to 10, then I can only have 10 movies in checkout status or on hold. As soon as I return a checked out movie or cancel a hold on a movie that will open up a spot and the system will automatically take the next movie in my queue and place a hold on it for me.
Then I am free to browse and search for all the movies I want to watch and throw them all in a queue. The system will work through the queue and track everything.
That's the basic idea. I've started working on prototyping it and building tests for portions of the code. But it's still a long way from being functional. I hope to have something usable for myself in the next month or so. If I can get some help (or enough time) to make the UI decent then I might open it up for anyone to use. Right now, I'm building this with the SLC city library, but also plan to support the SL county library too. I've designed it so I should be able to add more libraries in the future.
