Hahah I'm enjoying how this thread got derailed with classical music.
Actually, one of the most colorful moments in my life was getting to spend 15 minutes playing on
Vladimir Horowitz's concert grand piano. Needless to say, simply touching the keys was a humbling experience. The coolest thing about the piano was that he travelled around the world with it, and the keys were custom-tuned to accomodate his unusual straight-finger play style, requiring less pressure to push down.
Anyway, I mention it because the piano is still on tour around the US if any of you classical music afficionados are in the area and want to see it:

Aside from that, and getting back to the original topic, the things that stimulate me usually involve engineering. Everything from modern architecture to the air-combat capabilities of the F-22 raptop jet fighter. Awesome, AWESOME, stuff.
Travelling is another big passion of mine, which I'm sure I share with many others. But lately I've also become really keen on one day building my own library/study. It's so fun thinking about all the cool things I'd put in there

(it's not just going to be dusty old books ya know!)
