I really like the idea of using a hard surface as if it's water! So... just for fun, as an experiment... I decided to turn my very green desk into a little bit of ocean... SWIM FASTER HONEY!
To support my work and help me make more free stuff you can buy something from my Etsy shop: http://www.etsy.com/shop/macouno
Just be careful detaching the prints... I did them without support to create a nice smooth contact surface... but removing them from the build surface was tricky.
