QR Code with embeded image

QArt Coder is an online tool that allows to embed images into QR Codes.

QR codes are 2-dimensional bar codes that encode arbitrary text strings. A common use of QR codes is to encode URLs so that people can scan a QR code (for example, on an advertising poster, building roof, volleyball bikini, belt buckle, or airplane banner) to load a web site on a cell phone instead of having to “type” in a URL.

QR codes are encoded using Reed-Solomon error-correcting codes, so that a QR scanner does not have to see every pixel correctly in order to decode the content. The error correction makes it possible to introduce a few errors (fewer than the maximum that the algorithm can fix) in order to make an image. QArt Coder exploits that to embed an image into the QR code.

A Drawing ‘Bot Out Of Hacked Turntables

Two ordinary turntables are hacked to make drawings in the compelling art project “Drawing Apparatus.” The drawings produced by the contraption resemble old Spirograph images, and the simple DIY design of the device has an appealing vintage look and feel.
