Long ago I was looking into other Elemental based designs and sketched out some ideas on paper. Many I disregarded as either impractical or not overly interesting, including the 22 piece Neon based configuration in the lower left of the sheet below. I thought of this as the next extension of the Neon concept, completely skipping over a what should have been a logical six piece extension.
It's a good thing I have a smart friend with access to a laser cutter
VeryWetPaint took the DIY I sold him and decided to mod it by cutting the plunger tops to make a new piece. Why didn't I see this configuration! This adds six more pieces and (since Carbon has an atomic number of six) he decided to name it Neon Carbide.
It's very pretty:
One of the best things about this configuration is that by adding these extra pieces there are no more blocked moves (on Neon the plunger top blocks one other plunger from moving).
The one minor downside to this mod is that the edge pieces are not fully contained by the puzzle when a plunger is pushed. They don't fall out but wiggle a bit and so I thought this was an Elemental puzzle that deserved a redesign.
As such I present Sulfur (atomic number 16):
Not as cool a name as Carbon, but the six piece Elementals are not overly exciting. This is just the prototype so the pieces were unetched/inked.
It really looks quite a lot like Neon and is the same size (i.e. smaller pieces):
Yes, on this last one I carelessly inked an image on the front. It looks terrible but will be replaced.
P.S. For those with the Neon DIY: VeryWetPaint has access to a laser cutter and may have interest in selling an aftermarket Neon Carbide DIY mod kit
