My contribution is an enlarged version of the above GIF - retitled "Rotating Smile with Frame Removed" - that loops continuously for a minute. ("Militant, pointless redundancy..." Omigod magazine)
"Made In Internet" is described as follows:

...a showcase of short video forms created by web artists. This selection reflects the trends and concepts of contemporary new media in the last 5 years, which revolve around blogs, streaming video and social media: the late, consumer-oriented Web 2.0. In this new artistic universe appropriation is taken for granted, the attention span is short and the reward often takes the form of a conceptual charade. The works in the show stem from the web: they either have been created from found internet material or produced specifically for that platform.

Ramocki is giving a talk, "Assumed Mobility: Thoughts on Experiencing Time Online," and the PDF outline is here.
