I have trouble with Post-It notes. My handwriting is big ... huge, in fact. Can't help it. Regular, square-shaped Post-Its just don't accommodate my giant words. And when I brainstorm, I use oversized sketchpads to hold all my scribbles, diagrams and musings. In fact, I have a big sketchpad sticking out of my briefcase right now with page after page of work-related notes, mostly scribbled during conference calls.
Imagine how cool it would be to be able to use an entire wall for ideas, notes and diagrams. Now, this is an exciting possibility and it's available through a company called IdeaPaint. I don't know how well this works, but in the video, they make it look easy to literally transform an entire wall into a dry erase board. My second question is how hard it is to go backward and make the wall "normal" again, so as to be able to sell your house at a later date, for instance.
When my boys were little, we had a corner of the basement all fixed up like a classroom and they loved playing school. IdeaPaint would have been so cool! I've seen "paint" for creating chalkboards, as well. Wonder how well this stuff works.
