Ok this project is pretty silly but it was a fun experiment and is one of the pieces that visitors always talk about. I made a silicone copy mold out of my existing toilet tank lid and then cast a white concrete top in that mold using Quikrete countertop mix in white. I salvaged a bunch of desk lamps from an architecture studio and used them to make the adjustable arms. I then added different clips and hardware components to the ends of the arms so that they could hold different useful objects. This lid took about 3 hours to make and cost around $75.
