Reddit user spiderpark, is an avid wood carver. A pretty talented one too. He’s made some very detailed, small wood carvings:
That one is hard to see at first, but once you realize it, it’s right there. That is a very complicated highway intersection exchange. Viewing those from above is pretty cool, design your own though is even cooler I think. It allows you to vent all those frustrations you get when you’re sitting in traffic on the beautifully designed annoyance
That’s pretty easy though, an apartment building, or office building, but a building in general. Complete with two elevator shafts, one a service elevator it looks like.
He has an Imgur album with more photos of those two I posted, as well as a few other items, it’s pretty neat stuff.
