@adalger, do it!! jump on it, it is a lot of fun! in can pain any your walk in the gloomy day with iridiscent fun! @googlyeyes just recommended me an awesome "blu-tak" -- a reusable adhesive putty: https://en.wikipedia.org/wiki/Blu_Tack
in germany, he says, its coming from "Tesa" as a "poster adhesive" -- that stuff works really well on all kinds of surfaces...

you even may draw a pair of simple eye yourself! (I just asked my wife, and yesterday she created for me 2 pair of new eyes on a solid blue paper)

really, a lot of fun. and its a profitable contest! tho without your beloved SBI. oh, and also you may come to the disc channel and be one of the judges yourself!
