3D slider puzzle for children, but surprisingly tricky even for adults. Helps learn 3D problem solving skills. Similar in concept to the 2D "fifteen" slider puzzle. Written in Ada, this code compiles and runs on both OS-X and Linux. Now, improved function on laptops; runs on OS-X Retina displays too. New mousewheel zoom.
Too easy, you say? Try the 3x3x3 Rufas' Cube!
Anyone with OS-X or Linux and GNAT may recompile; but first try the delivered exes.
Mac OS-X or Linux with graphics card that supports OpenGL v 3.3
