Yay!!! I finally got pics up! but anyway, here is my cuboctatower that has probably already been made but maybe not I also made 6-color hex dipyrimid and 7 color confused pillow. so ya, here are the pics, the Hex dipyrimid and the confused pillow are already on ebay. and the cuboctatower will be soon.

It's a square antiprism. I was planning on making one with both sides 57mm per edge, but I didn't have any spare cubes to do it. Maybe I will now.

Andreas Nortmann made one viewtopic.php?p=156104#p156104

There's a sketch in the Jurgen Brandt section in Articles http://twistypuzzles.com/articles/spotlight-jurgen/

OK, already made, hey, it was a nice try at making a new mod. one of these times my idea is going to be original.....

It is not a precise antiprism. To be precise it needs to have squares of equal size.

@ENCuber:
I feel honored that you have (again) reinvented two of my mods.
If you want something new than delete the non-truncated faces of that cube by extending the remaining faces. I won't beat you there unless you need one year or so...

All three of the mods look awesome! Well done!

I almost forgot, Here are the links to the auctions for the 6 color hex dipyrimid and the 7 color confused pillow.
