So what can we OG3DS peasants do with homebrew?

Hi there, i've been lurking for some time and i'm naturally interested on homebrew, right now i have an original 3DS, no money to get a N3DS and i'm pretty confused about what can and can't be done on my little blue.

Let's say i have my O3DS with ironhax working on 10.1, is there anything i can do apart from changing my home menu theme?

Thanks!
