Stuck using the lightbox

[Brutus]

I got a new camera on the 20th of October, near a month ago, and I've found myself going back to the lightbox consistently, as it seems to be the most interesting place right now. I have a decent collection of knives, and so I have been taking pictures of them, and I've been pretty happy. I can't really go anywhere, being as I'm 16 and have no car, so I'm drawn to objects close to me, namely the lightbox. Anyone else been in this situation, stuck only doing one type of photography? Should I make more attempts at brancing out? I do like lightbox photography for some reason, so here's a recent photo taken just today, I'm happy with the even lighting I achieved (except for the very end of the knife, which is in shadow, shoudl've had a reflector there):

And another in the same lightbox, but with some granite. Since this was taken, I've realized a narrow aperture is better for small objects:
