A large supply of tan bricks, plates and tiles simply asks for more Lego versions of wooden 3D-puzzles. A very simple puzzle to build is the Altekruse puzzle because it exists of 12 (or 14) similar pieces. Easy to build with Lego, solving the puzzle on the other hand was a lot more difficult: I couldn't find a complete solution for this puzzle on the internet (I only found a guide to the solution, no detailed description), so I had to solve the puzzle myself. But in the end I figured it out.
Left: as usual I always design the puzzles first with MLCad.
Right: the the finished puzzle with 12 similar pieces.
Left: MLCad version of the 14-piece puzzle.
Right: by adding two more similar pieces it is possible to build a completely different puzzle.
The first time this puzzle was shown to the public was on August 10, during the 75th anniversary of LEGO.

Better late than never: I finally made some videos of my sliding puzzles, posted them on my YouTube channel, and embedded them here on my website.
The rendered images are created with MLCad and rendered with POV-Ray.
