This trippy building tool is a great way to kill a few hours

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.

One of my favorite features is that the castles are easily shareable — just copy and paste the link! There are already quite some impressive ones out there.

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!
