what should I do with these parts

I have a few two digit number LED displays and I cant think of any thing I should
tdo with them, so I thought that maybe you guys had any Ideas. And schematics
would be nice

Who says you need to do anything with them? Store them for later use. Looking for something to do with parts will tend to net you junk, typically you find a problem that needs a solution and then you see if what you have can solve it, if not collect more or buy what you need.

Well I like to build circuits in my spare time and found some of these displays
and I could not think of anything to use them for,
I don't mind buying parts they are very cheap,
