This is a 3d printed vase of a frog.
The files for design and printing can be found at:
Start with an object as a model (the little frog).
Draw a flat version and assign x/y coordinates to points along the curve. Using Autodesk 123d and a spline curve, input the points. Cut away everything outside the frog and "extrude" upward his face area. Add two spheres for eyeballs.
Save, print and insert your favorite flower.
