There are six regular convex polytopes in 4D, which are analogous to the
five Platonic solids in 3D. This is the fifth, the hyperdodecahedron, a remarkably beautiful object brought to my attention
by George Hart.
Here it's shown in a Schlegel diagram so you can see all 120 dodecahedral cells, though most are transformed by perspective: in this projection, the only regular dodecahedra are the biggest one on the outside and the tiniest one at the center.
A bigger model is here.

(Note: this model was previously erroneously described as bacteriophage T7, which has a different life cycle entirely and looks somewhat different. Sorry! I will update the name shortly after I work out how to preserve a few permalinks. Also, I have removed metal from printing options after a customer's order failed to print; sorry again!)
By request of @TheFrogBlog on twitter, here's a model of Bacteriophage T4 which is somewhat-accurate. Source files are on Thingiverse: http://www.thingiverse.com/thing:16496
T4 is a lytic phage which has been studied for years; a bacteria-virus that can infect and destroy E.coli cells within 30 minutes. Here's an excellent animation of T4 infecting an E.coli cell: http://www.seyet.com/bacteriophage-t4
