I didn’t know I was able to build flying 3D castles, but Science vs Magic developed a web tool that makes it possible.
Castles made of Castles is a simple web building tool that makes you the digital architect of weird, neon colored structures.
There’s only one important rule: every block you add is made up of the entire structure. This makes any end result extremely complex and close to killing my relatively powerful laptop.
The coolest structure I could come up with was this sad thing. I’m sure our readers can do better — share your creation in the comments!
