I don't know about unique, but here's what I do:

• I game on the PC or sometimes the XBOX 360.
• I chat.
• I occasionally go out, if I'm not having a bad day.
• I play the guitar.
• I'll go pester my dad, see what he's up to, and if I can help.
• I'll work on a project, like a website, a track, a guitar piece, etc.
• Practice/study German.
• Workout.
• Watch YouTube videos.
• Muck about on various sites I use, like PC!
• Watch a film, or programme, if my OCD/anxiety isn't too bad.
• Peruse sites like Amazon, eBay, PC World, and so on.
• Go on webcam and harass my brother.

That's basically most of the things I do when I'm bored.

Oh, and I'm a fairly decent guitarist of over 10 years, so if you have any questions, I'm happy to help.
