- People keep touching my screen, leaving fingerprints,
- My laptop has a touchcreen that I don't use.
Is there a program/driver that would for instance turn the whole screen red for 3 seconds every time a touch is detected? I imagine that would deter anyone from touching it again. Other implementations with the same goal are welcome too.
It should run on Ubuntu Linux. Preferably free.
The tool should not be rude, bonus for even improving the mood of the touchers at the same time, for instance by being funny. The point where the screen was touched could be highlighted to make the cause/effect more obvious. A Frozen-themed freezing of the screen starting from that point could be an idea. I would prefer to avoid sounds, in order to not attract attention from neighboring colleagues nor annoy them.
