Random plant event: Tradescantia spathacea flowers

I've seen these before, but this is the first one that was actually my plant. I've been thinking that this plant must be angry with me, lately, because I moved it a while back to a colder spot and it's been shedding leaves. But apparently if it's upset, it's not that upset.

This is another plant I got as a cutting from "hopefulauthor" at Garden Web (the first being the Schlumbergera mentioned here), in an exchange this summer, and it's the second of the cuttings from that exchange to bloom. There were also a couple cuttings of Ludisia discolor ("jewel orchid"), which are still alive: dare I hope to go three for three?
