This isn't an entry because I created this two years ago, but I thought I'd repost it here maybe as inspiration for anyone who's thinking about entering. This was entirely created in RayDream 3D -- which was the stripped-down, feature deprived version of RayDream Studio. Everything you see was built in the Freeform modeler (since RD3D didn't have metaballs or a vertex modeler), textured with limited procedural shaders or photoshop paintings.
I love the theme of the current contest. I hope I have time to finish an entry this time. (I started a donut entry but didn't have enough time to really work on it.)
