I made this a long time ago but never uploaded. It looks alright, I was a bit messy with the glue though.

The design has some very odd pieces used for some of the faces but I was careful to make sure that there is no ambiguity.
So.. while you may have no idea that a "? /" piece goes in the bottom-right corner, on that same corner piece is also the number 3 from a number keypad (which has an obvious position).

A true classic creation.
And it is black!

I've chucked this on ebay along with 9 other puzzles as a sort of "bulk puzzle" listing. I have too many puzzles that I simply never touch anymore so these are going to make some room!

Thanks, Andreas.
I'm touched!
