Exploding Kittens - First Edition Game
Game
Exploding Kittens is a highly-strategic, kitty-powered version of Russian Roulette. Players draw cards until someone draws an Exploding Kitten, at which point they explode, they are dead, and they are out of the game. UNLESS that player has a Defuse card, which can defuse the kitten using things like laser pointers, belly rubs, and catnip sandwiches. All of the other cards in the deck are used to move, mitigate, or avoid the Exploding Kittens.
This special First Edition copy of the game is a collector's item and will never be printed again. We hope you love it as much as we do!

G4G13 Logo Design
Art
Rec Math
This configuration of thirteen sets of concentric circles grows out of an ancient tradition of visual alchemy. The faculties of imagination and intuition are employed as guides in the discovery of new and meaningful relationships between geometric elements in a plane (on a flat surface). In this particular instance, the task was to discover a pattern representing the number 13 wherein harmonic symmetry is a constant. This configuration of thirteen color-coded circular rings answers this design challenge. Logic is also employed as part strategy in the creation of this pattern; a perfect example of the rich dialogue between right and left hemispheres of the brain. Let us remember that Mandalas are intended as two dimensional re-presentations of (ideally sacred) sounds.

Geometry in Five-Dimensions: Building Quasicrystals from Penrose Tiling
Art
No-one really knows what quasicrystals look like. But we do know, from the diffraction patterns of X-ray crystallography, that they bear a resemblance to Penrose tiling. By combining artistic exploration with mathematical insight into the five-dimensional nature of Penrose tiling we have begun to visualize the structure of quasicrystals.
We are building mathematically precise sculptures of Penrose tiling raised up to a dimension of somewhere between 2 and 5. We have also devised algorithms to explore two-dimensional aperiodic tilings using color and perspective. These drawings sometimes reveal structural patterns that become sculptures.
In January we built a mirrored glass and copper sculpture that attempts to reconstruct the crystallographic origins of Nobel prize winner Dany Schectman’s famous five-fold diffraction patterns.

Golden Magic
Art
My artwork, 'Golden Magic', especially created for G4G13 conference is dedicated to four remarkable men: Martin Gardner, Raymond M. Smullyan, Tom Rogers, and Al Seckel. Rich in golden mean proportions the composition consists of 13 elements placed inside a Penrose rhomb (P3 Penrose tiling) and displays an interplay of Penrose tiles (from P2 and P3 Penrose tilings), golden (Robinson) triangles, additionally decorated by a fractal pattern. Our minds' eyes can also be amused by certain optical instability.

How Safe Is It?
Rec Math
Magic
A spectator, with good arithmetical abilities, opens an invisible safe and deposits some invisible coins in it. The magician has the spectator do some arithmetic, receives the final result and then correctly opens the safe and retrieves the correct number of coins, except that the coins are now real!

Laser Cut Pythagorean Theorem Puzzle
Puzzle
Rec Math
A laser-cut puzzle that illustrates a proof of Pythagoras’ theorem. The puzzle pieces either fit in 2 squares aXa and bXb, or in a hypotenuse square cXc. The shapes in the puzzle are taken from a known proof of Pythagoras’ theorem. To my surprise the puzzle turns out to fairly difficult, often taking people about a minute to solve.
