Not sure what to call it. Saw one for sale on nuggetry: http://glass.nuggetry.com/add/a1392579803/#single-content ...and was perplexed by what looked like a handful of plastic tubes thrown into the bottom of the tube (and a model car tire?): Little research led me to this (includes function video): http://www.tiworm.com/2013/07/lql-glass-presents-jimmie-disc.html?m=1 Click to play YouTube Video Anyone see these before? Edit: I guess its called a "jimmie disc"? Edit 2: Moar pictars and function videos! Im starting to like how these work. Not so much a lot of their color choices though... http://pinsta.me/lqlglass @PhotoRider you ever run across these before?
