Here are a pair of models made with Sonobe units, but with a twist.  They are assembled "inside out", with all the tabs and pockets on the inside.  That completely changes the look of the model.  Actually, I usually prefer the inside-out look of these models - the colors break up along cleaner lines.  But they are a bear to assemble - especially the last couple of modules.  On the left is a 30-unit isocahedron, and on the right is a 120-unit icosidodecahedron.  For the icosidodecahedron, I used the pink and green to try to make it look like pink flowers on a field of green grass.  It stands out more in person - in the photo, you really only get to see one face, and can't move it around in your hands to get the full effect.
