Ok so I'll start with the thing Nate will like.
It's a binary clock. You read the time in columns as hh:mm:ss, ie in this photo it's 13:33:53.
The second thing I bought at a market yesterday for $2. The character:price ratio is off the charts. This thing was made by hand by some old dude, so it's totally unique too.
Finally, taking that previous photo reminded me that I've never actually photographed my authentic 70s electric organ*, which The Rab and the clock are sitting on. I picked it up at a market a year and a half ago for $20. It sounds amazing, even if some of the key springs are on the way out. I might have to take it apart and try to fix it at some point, but knowing me that will only end badly.
*At least I'm pretty sure it is. It's a nobody brand, so there's not much info floating around on them.
