Seven is NOT another Rubic's Cube. It's a whole new kind of puzzle. A 2x2x2 arrangement of cubelets with one missing allows sliding permutations. After a randomization, the goal is to restore the cube to its original configuration based on color and numeric hints. Dragging the cursor rotates the cube for a better view angle. Clicking the cursor on a cubelet adjacent to the empty space will slide it into that empty space. On laptops you may also hit <return> when the cursor is on the cubelet of choice to select and slide it. On MacBooks, a 2-finger tap on the touchpad does the job. As indicated on screen, <h> will toggle a help screen, and <c> will toggle color schemes. Works on Macs running OS-X and PCs running GNU/Linux.

* Important library update for Gnu/Linux users on 27% of distros that do not provide FLAC, ogg, vorbis libraries. Missing softlinks caused run failure. That is now fixed.
