Hoping to start on this around Christmas and be done sometime mid-late January. I'll post pics when available.
Interested to see the outcome of yours, love your idea and I plan on pirating much of your design for my own stand!
To make planning/customizing easier for anybody interested in using Sketchup, I've uploaded the model I made to their database. Sketchup is a free download, but there is a bit of a learning curve to it. Once you have it, just go to 3D Warehouse and Get Models. Then search for 29 Gallon Aquarium Stand. It should be in there now.
