Prevent markers from spoiling projector screens Printer Friendly Version
How many times have we seen ugly marks on overhead screen projectors?
A simple idea would be to place a (fixed) glass/plastic fibre sheet in front of the area of the screen. That way, when someone (unknowingly) tries to use a marker on the white screen, the damage is not done!!!

Office chair rolls that don't ruin the floor Printer Friendly Version
Ok, now I know that there are various products out there that are supposed to do the job. There are softer rolls for hardwood floors that supposedly don't make any scratches, and there are even stumps that you can use instead of rolls (stick some felt underneath for protection). But if you've used those, you will notice that they are actually only joke articles - the floor will still suffer, and even more if you trust the manufacturer's promise and aren't as careful as you really should.
So how about inventing something that really, truely, sincerely, reliably doesn't scratch the floor when you move around with your office chair, even if you're a hardcore office worker and eat & sleep on the chair? Hover craft or magic levitation could do the trick, but I'm sure there are other ways. You could fasten the seat on an arm that's screwed to the wall (although admittedly that would be an expensive solution). Aren't there any high-tech materials that can be used for the purpose? And if yes, what could keep tiny stones or other pieces of hard material sneaking in between and causing scratches anyway?

Transparent post-its(R) Printer Friendly Version
Those yellow and other multi-colored message slips are good for drawing attention to themselves and the messages written on them, but what if the information BEHIND the message is also important? Transparent post-its could work to temporarily modify other printed information like calendars, other printed posters and signs, books, etc. Using material similar to transparent tape, but with the removable adhesive should make this a simple and useful innovation.
