I really do enjoy looking for odd reflections. I did this experiment once where I papered up all my mirrors in the house, and disciplined myself not to look in any external glass (like that of a passing car) - what would happen if you stop being able to see your own reflection?
It's stranger than you might think - even if you're not prone to philosophizing during the experience, the moment when you finally re-greet yourself is oddly scary, and isn't like the proverbial band-aid coming off: the moment, moments, linger.
Other things have reflections too. This is the reflection of my girlfriend's car in my car. :)
