I've got a box o' toys - a couple oh glass pieces, a usb bullet that never needs batteries, a rabbit, and a few other things that buzz.

Not Lil, but to answer the question on glass - it has a firmness that can't be matched by anything else. I also like that it's easy to clean, can go hot or cold. It's just a darn fun toy.
