Here's one that flew under the radar last year and just now got sent over to us! ChronoSFX over on Deviant Art decided to craft his daughter a Rainbow Dash themed Dalek for Halloween. A combination of wood, cardboard, and foam makes up it's exterior with moving weapons and working lights.
Head on down below the breakf or a few more images of it!
Thanks to Xanni the Wired and Wonderful for the heads up.
