Ask HN: What cool desk ideas do you have for a home office?

I’m in the market for a new desk but I’ve decided I’d like to build the desktop out of wood and buy a height adjustable base. If I’m building it I want to do some interesting, unique, functional things. For reference I’m a software engineer and I’ve been working from home for 4 years with a pretty basic height adjustable desk. Assume I can build anything. That isn’t true but I’ll try :D
