[matthew venn] shows us how to create this cool RGB LED lamp. There’s nothing groundbreaking here, but some good information on casting the base out of concrete. The body of the lap is formed by two thin rods folded in half, stuck in holes in the base, with a lycra sleeve slid over them. The final effect is quite nice and can be controlled by 3 knobs recessed in the front of the base. Information on the actual circuit used is very limited, as there are so many tutorials out there for that, but he does show how he mounted it all, and plans on releasing the source code soon.
