I haven't done a proper project in a long while, and this past weekend it finally got to me. So I decided to try my hand making a prop/replica of the tuberous AI from Portal 2. I give you Potato GLaDOS : Most of it was sculpted from Sculpey and painted with acrylics. The audio comes from an old mp3 player I had lying around. The electronics consist of a LM386 audio amplifier, speaker, LEDs and a simple circuit to pulse the LEDs with the audio. Here's a long winded explanation breakdown of how it was made . There's a boat-load of build pictures out on Flickr. The audio was pulled from here and spliced together in Audacity . Please support the developers and artists of these amazing games: Purchase Portal 2! And remember: "This. Sentence. Is. FALSE".
