I've liked Flux since I learned it at the CZT seminar I attended in May 2010. At that time Flux was Maria's version. It was joked that Rick had difficulty doing the little indent before continuing with the shape. Maria jokingly called his attempts "Tongues" in reference to a Rolling Stones album. Another student at that seminar remarked, "It looks like purslane." and I've thought of Rick's tongues version as Purslane since that time.
Here's Maria's Flux with some of the additions I like to include, especially if the round ends are large: a spiral end, little droplet 'stems', and a zigzaggy thing. There's also Rick's version (Purslane).
