So these just showed up in my living room....

Should I be worried?

( Okay, it took a little more time than that for them to arrive. 8 pics below the cut )

So that's cubes 101. I started with 2 7/8 by 2 7/8 by 2 7/8 and after coating them ended up with 3x3x3 inch cubes. They might be a little bigger than the ones on the show, but I am still pretty satisfied with them.
