I don't usually make clone games but after playing Microsoft's "Pandoras Box" I really wanted more of the "focus point" type puzzles.
Essentially, the game takes a raster image, divides it into various rectangles then shuffles all those rectangles throughout differently sized regions on the screen.
The natural effect is that you use the pixelization and stretching as hints of the original dimensions of each piece for placement.
I use Linux and I imagine most folks here are on Windows or MacOS so I'll simply provide a video and the source.
I've written this in BlitzMax NG so there may be some incompatibilities with ye olde BlitzMax.
