Fluorine
Designed and sold by David Litwin, 2012.
(laser cut plastic and stainless steel screws, 5.5" tip to tip, 3/4" thick)
This puzzle is beautifully custom made from layers of laser cut plastic.
It is a successor to the
Elemental Neon
puzzle,
and like that puzzle:
-
A
middle plunger
that moves horizontally is crossed by
left
and
right
plungers.
-
The plungers can be moved to rearrange the red tiles in the center through which a pattern of 4 circles can be seen;
it helps to do this under a light so the pattern is easier to see:
-
Rotations of the triangles to mix up the tiles; then restore the pattern.
-
Fun to use and harder than it looks at first.
Here are photos of each of the three plungers moving
(and for each, the plunger can also move in the opposite direction):
