Slide-together Models

We have recently become quite entranced by the quality of the 3-D models that can be made with the simplest of equipment - coloured card and a pair of scissors.

This picture is a Great Rhombicuboctahedron, one of the 13 Archimedean solids that can all be made with slide-togethers. 

If you follow the link at the side, you can download a basic slide-together kit ... and it's amazing what even a few shapes can be transformed into.

Sudokus and Excel

If there is any one thing that has really caught on in the past year or so, it just has to be the Sudoku puzzles. Did you know that Sudokus originated in Japan where their script makes it impossible for them to enjoy crossword puzzles! So they came up with a range of number-space puzzles and of these, the Sudoku has become an international hit. 

Our small contribution to the field is a spreadsheet that lends a hand just when you're thinking that the puzzle can't be solved. So if you're stuck on a Sudoku or on Sudokus in general why not try out our Excel spreadsheet that is sure to guide you to the solution.

Hexagonia

As a result of continuing investigations, we have put together a collection of facts and problems based on the hexagon ... and we hope that you have a moment to explore what we have found out. Click here to begin!
