The other day I came home to find my wife had turned one of my endless stream of incoming Digikey boxes into a fort for the cats. It had a large front door, windows, a small back door, and even a second story perch inside!
It was pretty crafty, but needed some personality. So while she was away on a work trip I decided to bling it out a bit. With the help of google image search, a laser cutter, and some cardboard I turned it into a medieval stronghold.
For those without access to a laser cutter, the details could also be cut by hand. Either way, it is great just to see an example of the crafty potential of using a laser cutter with salvaged materials.
