While following TrustFlow recs* I discovered that Ernie's 3d Pancakes has an LJ mirror: [info]__ernies_3d_pan. One more to move from my RSS aggregator to my flist...

* Actually not so much the recs in that post, but an updated set after I found origami math prof [info]tomster0 in the first set and added him...from the updated set I found [info]bramcohen, from whose profile I found this. Aren't social networks fun?

ETA: While I'm finding mirrors of geometry streams: [info]geometryjunk and [info]geomblog_feed.
