Last week I built a tomogachi like smart contract. Today, I added the functions to frames.
None of it really works yet, but it is neat as a proof of concept.

It would be nice if I could post in /ai since I built this with AI, or /frames since I built this as a frame, but only members can post in channels.

Back in the good old days any sort of in frame app would have gotten interaction and an in frame tomogatchi would have been pretty crazy viral. 
Nowadays? 
1 singular like. Granted, it's not 110% functional though the example and wire framing exist for anyone to take.
