Not super super great, but Reverie from Planetarian.
I think more of the ribbon part could be interesting, since it could light up, and read words through it, but I don't think we have that kind of technology to get what she has going working.
Cosplay 1: Sailor Venus (Commissioner failed to make 4 month deadline)
Update: August 10th.... still nothing.
Reality: Recycled or no cosplay at all. Got to love commissioning! Thanks everyone!! Serious thanks to Dulcinea, who actually made the deadline for the accessories far in advance and of outstanding quality. Sucks they won't be used.
