My halloween costume this year. It is a full scale dalek hero prop replica made from fiberglass, aluminium and rubber.
I did not quite manage to finish it on time due to a disaster with the trundling mechanism. The eyepiece is dodgy and dalek aficionados will not the absence of plunger and gun. Given that fitting them requires careful measurement and is a one time thing, I did not want to rush it.
The voice is produced by an authentic Moogerfooger ring modulator as used by the BBC that I bought off EBay.
