For years I've thought about doing an "art project" to make people more aware of the fact they are being observed – but I never actually got up and did it.

The idea was to seek spots in the city where public web cams are pointed at, and paint QR codes on the ground at those spots (using a template), linking to the camera stream. So when curious passerbys scan the code, they see themselves in a camera stream and feel "watched".

"... and paint QR codes on the ground at those spots ..."

This is what "Oh By Codes"[1] are for.

Instead of trying to paint a QR code, which is difficult, you can just chalk a 6 character code.

Further, you can create them on the fly without using a special tool - just a textarea on a simple webpage.

You can encode up to 4096 characters or a single URL redirect.
