Looking for a "remote control" look

Ive put together everything I need for IR communications for a bunch of equipment. Works good, and I’m excited to see it come together. But at this point all ive done is cobble it together with basic buttons. The layout looks fine and I don’t have any problems with it. But I’m just now starting to venture into the idea of custom cards and themes. So I was wondering if anyone here has already done that? Maybe something I could add in, or build off of.

Thanks!
