Software Design and Home Depot, who would have thought they went together so well.
Back in the contractor lab at Microsoft we used to joke about a room made entirely out of whiteboard material. A friend of mine told me you could get entire sheets of the stuff for cheap at Lowes or Home Depot, but I never could find the right material. The other day I decided to take a look and sure enough, 2x4 foot sheets of whiteboard material are only $5. A 4x6 whiteboard can cost you nearly $100 at a place like Staples, so there is definitely some savings in buying the raw material.
I only bought about 4 sheets, so the entire room being covered is a ways off. However, I found better uses for the material than just covering your walls. You can cut 1' square sections and use it for just about any software design you could think of. A single sheet cuts out 8 and you can draw something, plastic wrap over the top of it, and store it for later or simply wipe it off and use it again. Being as I'm working on my latest book, having a small portable drawing device (don't even start talking about Tablet PC's, they hold no water compared to a good old whiteboard and some markers) is coming in really handy. I pounded out an entire chapters worth of figures in only a few hours this weekend, something that would have taken me a couple of days in Visio. If I steady my hand a bit, I could even use the drawings inside of the chapters rather than later transferring them to Visio (I'm always quick at laying out something I've already designed, but designing something in Visio is a real pain compared to drawing it by hand).
Well, we'll see what my publisher thinks about the quality of the sketches and go from there I guess. If nothing else, I'm happy with my $20 purchase of a nearly limitless area for mathematical equations, software design, and grocery lists (oops, how'd that get in there).
