Our cabinet is completely unrecognizable from the original design. We replaced the left chamber, the right chamber, the left chamber again, the entire logic of the solution, the track shapes, the bi-arms and a hexarm, and the cabinet's wood for good measure. This started out with 84 instructions.

The piece de resistance is the pair of "magic" arms that assemble all three different products, with pivoting help. We at one point had a single magic arm to handle a special case, but it was more efficient to handle three special cases.

Possible areas of improvement are using a more ambitious track shape such that a magic arm performs the right chamber pivoting work incidentally, or a similar concept for the left chamber. Right is unlikely, since the tracks and arms are constrained. Left is more viable, but we still could not find a solution, and it would require a right chamber redesign regardless.

It's intriguing to revisit these outdated theories of alchemy. Do you remember the days of "metal zoo" theory, where dozens and dozens of alchemical prime metals were postulated? It's true that there are rare primes, such as Uranus's metal, but the zoo was even less plausible than quark theory.
