This puzzle is 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. 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.
