RATTLEBACK – GAEL
Reclaimed Wood
Decorative assembly: Tongue and groove
Dimensions: About 25 cm (10 inches)
Code: M80
Model for business gifts. Several colours available.
Also available in a larger size for museums and universities (from 23 inches up to 8 feet long).
This rattleback model is very spectacular. The inversion motion of the spinning direction is by far the fastest and the most confusing of any other kind you may find. I invented this type of rattleback with joinery to augment its atypical motion. The results have surpassed all my expectations. The behaviour of this object really seems to go against the laws of physics.
RATTLEBACK – Dragons
Each rattleback has a mind of its own…
Some spin only clockwise, others only counter-clockwise. If you try to spin it the other way, it wobbles and starts spinning in the original direction!

Dimensions: About 20 cm (8 in)
Spinning direction: Counter-clockwise
These two intertwined dragons on the rattleback are a reproduction of the Book of Kells (9th century). They are each looking in different directions. Which way should they turn?
ANAGYRE – Doggy
Each rattleback has a mind of its own…
Some spin only clockwise, others only counter-clockwise. If you try to spin it the other way, it wobbles and starts spinning in the original direction!

LEAF CONCERTO – musical toy
This tree shaped musical toy sounds similar to a xylophone. Place the marbles at the top of the tree and they will make each leaf ring as they descend.
The motion path of the marbles is never completely the same. The challenge is to make all of the marbles tumble down without straying from the motion path surrounding the trunk.
This sound game for all ages is also a decorative piece that never fails to impress!

LEWIS CARROLL BAFFLING PUZZLE
Rules of the Game: Reshape a square on the same surface with one piece less than in the starting configuration… Illusion or geometry?
The principle of this puzzle draws on a discovery made by Lewis Carroll (Charles Lutwidge Dodgson), mathematician and author of the famous 1865 publication, “Alice’s Adventures in Wonderland.”

HENRY DUDENEY DESK CLOCK (USA-MADE MOVEMENT)
This Art Deco style clock is a rare and original object.
It conveys the idea that the plans we make sooner or later turn out differently as time goes on.
This 4-piece division was invented by the mathematician Henry Dudeney in 1902.
It is based on the Lowry-Wallace-Bolyai-Gerwien theorem which states that two polygons of equal area can be endlessly transformed into one other by dissection.
This theorem paved the way for minimal geometric division, which is a science that is as difficult as it is imaginative.
To this day, Henry Dudeney holds the record for minimalism since dividing the triangle-square into 3 pieces remains a mystery.
