The first element in a whole series of puzzles working with plunger under- and overlapping each other.

A puzzle with an innovative mechanism. 10 triangular pieces (divided by orientation in sets of 3 and 7 pieces) are moved by a system of three plungers which both can move into two directions.
The symbol distributed between all 10 pieces is the warning symbol for Biohazard. This gave the puzzle its first name. Later several other similar puzzle were designed by the same inventor and this puzzle was renamed to Elemental(Neon). Hereby Elemental is the names part which is shared by all the puzzles with plungers.
The puzzle is made with laser cut pieces. Although there are now more than 100 samples of this puzzle out there the inventor still builds them by hand. Every puzzle is imprinted with a serial number on its back and a wide variety of of designs with other symbols, different colors, has been made and even more can be ordered from the inventor.
The puzzle has 15120 permutations.
This puzzle attended the design competition during IPP28 in 2008.
