13 Jun 2011: We're a bit late for this month's polytope again, but here it is:
This is the cantellated 5-cell, a member of the sweet and simple 5-cell family of uniform polytopes, shown in two 4D viewpoints. It is bounded by 5 octahedra, 5 cuboctahedra, and 10 triangular prisms.

Added a high-resolution perspective projection of the rectified 120-cell, showing its 120 icosidodecahedral cells:
And for dessert, we have a cool animation of the runcinated 120-cell's dodecahedral cells rotating in 4D:

We're a bit late for this month's polytope, but it's never too late! This month, we present another member of the beautiful family of uniform polychora with 120-cell symmetry:
Behold, the rectified 120-cell! This “mugshot” shows the subset of its 600 tetrahedral cells that lie on its “northern hemisphere”, colored in 7 layers. It also has 120 icosidodecahedral cells, not shown here. Find out more in the rectified 120-cell page!

1 Apr 2011:
For the month of April, we present the runcinated 24-cell, another beautiful member of the 24-cell family of uniform polytopes, bounded by 48 octahedra and 192 triangular prisms.
Also corrected an error in the uniform polychora page: the omnitruncated 24-cell is bounded by 192 hexagonal prisms, not octagonal prisms.
