We've been experimenting with the laser cutter to see what we can create. 

With a gear generator tool built by Dzl and an ability to draw some shapes, we created "Steampunk butterflies" and the very geeky steampunk backpack for a costume party.

The laser cut butterflies and gears were made from ikea packing materials, namely, the leftover cardboard that our new costume closet (wardrobe) came in. We thought we should give them a second life and so we decided to laser cut and spray paint gold the cardboard which gave it a really nice look.

Also used some of the extra butterflies as eye makeup:
