Wow! They look extra big, or is that my imagination?
They are made from ordinary pucks. Nothing special, even the size is "normal".
How come the 2nd isn't worth presenting?
Transforming a puck into a dodecagonal prism. This must be one of the easiest shape mods possible.
The first can be considered puck "2x2x2", not?
The 2x2x2 is more difficult than this star prism. But I think I got what you want to say. And yes, it is a puck with less pieces compared to a normal puck.
