Thanks Laura, I've been meaning to check to see if the workshops were posted yet, but keep forgetting. If there's anyone out there that lives withing driving distance of this event and hasn't gone, you are really missing an excellent opportunity! There are some very very knowledgeable people giving some of these lectures. In some cases, you can get a CliffsNotes version of a semester worth of information in just an hour. Be sure to come by the Iris Society's booth and say hi while you stock up on some iris rhizomes. I'll be there Saturday morning.

Oooh that's hard! My screen has value differences (which is what's being tested, not color differences) from top to bottom, and also some from left to right because it's angled. I got 28 but then had a black one and couldn't find it. I tried again with the display centered better, and still got 28 even though they were in a different order. How do you get 33? It stopped at 29 for me.
