What’s up with the dude dancing at Richmond and Timmons?

For the last few months, every time I go by the Richmond x Timmons intersection (which is a nearby daily), there's this dude dancing the day away on the median across from Oishii. He's not intrusive or dangerous, but just there every day. Usually from like noon until like 2a, from what I can tell.

I don't think he's homeless, mostly because he's in a different outfit every day.

The one time I tried to talk to him, he just seemed upset that I ruined his vibe.

Just curious as to what this dude's deal is. Like, why that corner? Why not some place in doors?
