Reliquarium is a unique set of four 3D geometric slider puzzles for kids, all with a Crystal Skull theme. It runs on Windows, GNU/Linux or Mac/OS-X. Reckless raiders have plundered a tomb and displaced an ancient relic. The objective is to return the relic to the center of its cubical box by rearranging the numbered blocks back into their proper order, which also represents a proper RGB coloring...Red in the X-direction, Green in the Y-direction, Blue in the Z-direction. Dragging the cursor rotates the cube for a better view angle. The mouse wheel zooms. Typing a number 1..8 selects a block to move, 0 selects the relic itself. Then use the keys {u,d,l,r,f,b} to move it. The proper command to extract the archive and maintain the directory structure is "7z x filename". These unique puzzles are spatially challenging, yet easy enough for children and will likely help with learning 3D visualization, geometry, problem solving and computer skills.
