I really like the "funky dice" that get used in Dungeon Crawl Classics [1], like the D5 which shows up here. Also, it's probably worth noting that Lou Zocchi had at least four major iterations of the Zocchihedron (d100), with different braking mechanisms, and that they're basically impossible to obtain in the last couple years. He lost a fair bit of his work in a fire [2] and had some major health problems [3] last year as well.
As a sidenote, I'm not sure why a d216 hasn't ever been made -- that one feels like a fun (novelty) opportunity to replace 3d6 for attribute rolls.
I saw a Mk II once and it definitely would brake well on a soft surface. It was still hard to read though. I always wondered if putting a liquid with a small bubble between the numbers and the outside would yield a cursor for reading the number. Still 2d10 is more practical.
Rather than a d216 you then need a conversion table to use, why not a 16-sided dice numbered 3-18 that has been weighted to roll the appropriate distribution?
