A simple modification of a 2x2x3 to get a triangular prism representing the Greek letter Delta.
This puzzle is a prism of an Isosceles triangle which was reached by first truncating and then extending a mass-produced 2x2x3 cuboid. The name "Delta" is meant to be an allusion of the Greek letter which is standing for a mathematical symbol as well as for the inventors initials D.D. Although the puzzle seems to be quite symmetrical it can change its shape very fast.
