Quit talkin' and start chalkin'

You may have seen some (or all) of these pics before, in fact I've even posted on them in the past, but it's still pretty interesting.

Sidewalk chalk art that gives the illusion of 3-D. Note that just about all of these drawings require a very specific viewpoint; if you stand anywhere except from where the camera took this picture, the drawings would at best look distorted and possibly even nonsensical. The last two pictures in the set make just that point.

Do they really outline the dead body in chalk at a crime scene?

Get it off your chest and onto your cup with this chalkboard coffee mug.

Tightfisted, miserly pennypinching Thrifty folk might enjoy making their own chalk using Plaster of Paris and tempera paint.
