What should I do for a collage - photography?

Question: What should I do for a collage - photography!?

I have some ideas, just looking for a few others!. I need to get at least 30 pictures for it!. It can be anything, from shoes to family!. I would prefer not many people need to be in it, though!.
It's winter where I live and I can't go strolling on the streets since we have no sidewalks and barely any stores!.Www@QuestionHome@Com

Here is one that you can do inside where it is warm! :-)

Switches!. I have been thinking of doing this myself!. Just get well composed, well lit shots of all the various switches in the house!. You would be amazed at how many there are!. Computer on / off button, lamps, wall swiches, tv, remote controls, kitchen appliances, hair dryer, etc!. Just look close, you will find plenty!.
