Are there "tricks" I can teach this cat to engage more with her?

Where I now live, there are three cats, and one in particular seems to have adopted me. She’s just over a year old, very agile, very vocal and seems to love company. I’m working on teaching her to use the scratching post rather than the sofas, and she’s responding very quickly to this.

Naturally,now I feel like she has become my cat I’ve decided she’s a bright young thing, and wonder if there are other things I can teach her that would challenge her little brain in a good way? It would be sad if she became solely a lap-cat too soon.
