Mrs. Shepherd and others pointed the fact that the new logo of POET is a ''Schematic of an optical thyristor, squiggly lines are photons going in and out, straight lines are electrical'' (http://agoracom.com/ir/POETTechnologies/forums/discussion/topics/577419-note-the-avatar/?message_id=1812011#message_1812011).I don't think POET chose it for nothing, certainly not for his estheticism...

I was trying to copy/paste the things I found interesting, but there is way too much informations.
Also, in a old message, I was questioning why they removed the optical validation. I was wrong, they did not. They just changed the terminology of Milestone 7.
