Rhizome has a post about a self-deleting website:

Virtual data isn’t subject to decay like traditional media. Despite this, we can still lose personal data to disk failure, viruses, or accidental deletion. Unlike personal data however, data on the internet has a seemingly infinite shelf-life. Between search-engine caching, cloud-hosting, re-blogging, plagiarizing, and the way-back machine, the net collects and eternally stores vast amounts of information.

Temporary.cc eschews this paradigm. For each unique visitor it receives, Temporary.cc deletes part of itself. These deletions change the way browsers understand the website’s code and create a unique (de)generative piece after each new user. Because each unique visit produces a new composition through self-destruction, Temporary.cc can never be truly indexed, as any subsequent act of viewing could irreparably modifiy it.

Eventually, like tangible media, Temporary.cc will fall apart entirely, becoming a blank white website. Its existence will be remembered only by those who saw or heard about it.

That’s certainly one way to look at erasure.

It has projects created by people in many countries – some trying to visualise energy consumption in their  homes, others with more interesting ideas.
