N-dimensional sequential move puzzle have succeeded in finding them on all similar puzzles that have so far been solved. A 2-D Rubik type puzzle can no more be physically constructed than a 4-D one can. A 3-D puzzle could be constructed with no stickers on the third dimension which would then behave as a 2-D puzzle but the true implementation of the puzzle remains in the virtual world. The implementation shown here is from Superliminal who call it the 2D Magic Cube. The puzzle is not of any great interest to solvers as its solution is quite trivial. In large part this is because
Lucid 3-D Lucid 3-D Lucid 3-D was a spreadsheet package that began in the MS-DOS era; Windows support came later. Sam Redman and Michael Stanford incorporated as PCSG corporation (Portable Computer Support Group). Their Lucid 3-D spreadsheet was marketed by DAC. Lucid 3-D was considered noteworthy at the time for being "the only major memory-resident spreadsheet available for the PC." The selling point of the product was being "three dimensional. "Any cell" of the spreadsheet "can contain a complete other spreadsheet that you can access with a single key"stroke." Another technical feature was what their ads called "not only minimal recalc, but
