Lou e-mails with the answer to my little artistic dilemma.

She points me towards the Variable Media Network which (ready, art lovers?) "pairs artists with museum and media consultants to provoke comparison of artworks created in ephemeral mediums. The initiative aims to define each of these case studies in terms of medium-independent behaviors and to identify artist-approved strategies for preserving artwork with the help of an interactive questionnaire" (haven't they got anything better to do?)

You see, it's all about storage, emulation, migration and reinterpretation, don't you know.
