Think Geek's Vilcus Plug Dactyloadapter has some great product pictures and even better copy. Designed by Art Lebedev, the developer of the Optimus Maximus keyboard, it's being marketed by Think Geek as a tool — inspired by various Soviet-era KGBA "persuasion" devices — that lets any one quickly and easily test the functionality of any electrical socket. Lebedev himself is being less coy: "Vilcus dactyloadapter was developed specially for people who enjoy closing electrical circuits with their own fingers." For example, a sensuous duo of Castro Street electricians.
I think it's a great gag product, especially for $12.99, but what I find more interesting about the Vilcus is the fact that it must be safe... or at least, safe enough that Think Geek isn't terribly worried about selling it, their bolded humorous legal patter aside. Fantastic bullet point features include "Exclusive Russian Design" and "Become more alert through free electroshock therapy."
