Prosthetic Knowledge Picks: Slitscan
A collection of examples from the Prosthetic Knowledge Tumblr archive on the subject of Slitscanning, a photographic effect that creates distortions and occasionally insightful images based on time.
The slitscan effect has, of-late, had something of a renaissance over the past year thanks to digital technology. Once a time consuming and expensive technique, coders have created their own solutions (either personally or commercially in the mobile app market). For the uninitiated, it has been defined by Golan Levin thus:
Slitscan imaging techniques are used to create static images of time-based phenomena. In traditional film photography, slit scan images are created by exposing film as it slides past a slit-shaped aperture. In the digital realm, thin slices are extracted from a sequence of video frames, and concatenated into a new image.
Below are some examples of creative coding with the slitscan technique:
Volumetric Slitscan Experiments by Memo Akten
The slitscan technique is a well-explored method in photography and video, but this is the first time I have seen it using a Kinect camera feed, where depth plays an additional factor. Two short videos are embedded above, and they are made more fun by the music (dancing to Nina Simone’s “My Baby Just Cares For Me”).
Work-in-progress prototype for an upcoming project involving volumetric slitscanning using kinect (should it be called surface-scanning?). Similar to traditional slitscanning ... but instead of working with 2D images + time, this technique uses spatial + temporal data stored in a 4D Space-Time Continuum, and 3 dimensional temporal gradients (i.e. not just slitscanning on the depth/rgb images, but surface-scanning on the animated 3D point cloud).

Prosthetic Knowledge Picks: Commodore Christmas Demos
In this submission, we take a look at how a holiday season was expressed through the Commodore 64.
Released in 1982, the Commodore 64 was, at one point, the biggest selling computer ever, selling up to 17 million units in it's time. As a retail-focused product (as opposed to an electrical one), Christmas was an important time to attract this highly desirable present. As well as this, groups and communities around the machine emerged, creating shareable demos of images, animations and music for themselves, a highly humanizing response to a digital technology. It's happened with other machines as well (the ZX Spectrum, the Amstrad, various Atari machines, the Amiga etc ...), not just in it's time but also currently where communities exist around these older technologies. It also happens around file formats, for example, with the GIF net art community and the GIF Wrapping project where artists randomly selected together to produce something for each other.
Commodore 64 Christmas Demo (1982)
This charming demo was created by Commodore themselves, shipped to retailers to demonstrate the graphical and sound capabilities - via csixty4:
Commodore wrote their famous Christmas Demo in 1982 to demonstrate the capabilities of their new Commodore 64 computer and the upcoming Executive 64 (SX-64) portable. It was included with the test/demo disk that shipped with every SX-64 so dealers could introduce customers to the machines' advanced (for the time) sound and graphics. Though its character graphics and SID sound seem quaint by today's standards, the Christmas Demo reminds many Commodore fans of the morning they woke to find a computer under their tree.

Prosthetic Knowledge Picks: The 3D GIF
Sample from Animated GIF in 3D
This has been a good year for the Animated GIF— not only has it reached its 25th birthday, it has also become America's word of the year according to Oxford Dictionaries USA. It has been one of the internet's most creative canvases since it's availability, whether it has been employed in early homegrown HTML pages, to communities such as B3ta, YTMND, 4Chan and others. From it's continued popularity, some creatives have explored ways to take the animated GIF into new contexts. Here are a few examples:
