Lychee Tetris Constructible Three dimensional squares
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
You can make a rectangle as long as you don't use all of the pieces (maybe that is part of the puzzle?). For example, from http://www.amazon.co.uk/Lychee-Tetris-Constructible-Three-di..., remove the purple piece, shift the red piece to the left one space and flip it, then place the blue piece vertically on the right hand side.
The article links to it in the first sentence also: http://www.amazon.co.uk/Lychee-Tetris-Constructible-Three-di...
