"Power corrupts. PowerPoint corrupts absolutely" - Edward Tufte.
So, if PowerPoint is evil; the fightback begins here. Think of this as a wholesome, good karma form of industrial sabotage. All that is required is a careful (furtive) insertion of this image into various PowerPoint presentation decks belonging to either 1. You (excellent place to start) 2. Your co-workers, 3. Your boss, 4. Your competitors, 5. Your parent teacher association organiser, 6. Anyone who comes to 'present' to you at your place of work.
This should create the required disturbance in the PowerPoint forcefield and, with a little luck, force them to let go of the wheel and actually talk to you as humans without the crutch of 78 slides to make a point that should take only 3.
Please do come back and let me know how you get on with it.

PPS. My trackbacks are not working, otherwise it would have been obvious to me sooner that this post has since been covered in the latest Geek News Central

PPPS. It did also occur to me that not every projector is running in English, but I don't know / haven't checked what 'No Signal' is in other languages. Also, if you wanted to be very accurate/convincing, you could copy specific projector manufacturer graphics and logos into a variety of different No Signal messages for various projectors. But that's getting too anal. Indeed, it would also be fantastically ironic to eventually end up with a multi-slide deck of countless 'No signal' slides in various languages and brands. Excellent recursion.
This was just about the idea, not so much the execution - which is easy to customise on your own for your own needs.
