Four D Puzzle

This puzzle is nearly impossible to portray in a photograph. Its a visual mind bender. Have you ever seen that drawing of the guy climbing the endless staircase? This puzzle is like that, it seems to move in and out of 3 dimensions into a 4th as you look at it.

Even when dealing with the pieces it messes with your mind a bit. Everything, even the presentation base, is at a weird angle and it becomes mesmerizing. Pretty to look at and and a top notch desk puzzle.

Of moderate degree of difficulty. Measures 4.25" across and about 2" high when assembled. 9 pieces plus the base. Very unusual!
