I've just had my first post on my site from someone I don't know in 3D! So far the only comments have been from my roommate! So... I think it's only fair that I answer the question posed.
A couple presents I've given... there are two children's books that my mother adores and has never bought for herself. I managed to find one of them "Tikki Tikki Tembo" but couldn't find the other "Maggie B." I got her the one I did find and that was really nice.
For my roommate's birthday last year... there is a CD of mine that she was ALWAYS stealing. So... I bought her the movie that it's from. Oh, the name of it is "Alegria" it's a movie that uses the Cirque du Soleil show as the backdrop for the story of the movie.
There have been others, but that's all I can think of right off the top of my head!
