Something I wore last year to a local convention (general science-fiction, about 2300+ attendees):
You'll have to excuse the feather color, but it was also used in a very odd Mardi Gras float. The theme was "Rock 'n' Roll" and a local artist guy had a Learjet fuselage and wanted to do Tina Turner. You know, Aunty Entity. I had pics and links on here but they seem to have been lost in the purge. Might be able to find them again.
