Lucas Czjzek has approached media-mimetic biology in a more explicitly mechanical fashion than other works, and it’s the stronger for it in my opinion.
21 irradiated petri dishes containing yeast cultures are cycled within a cabinet. Several webcams combine the 3 stacks of spinning dishes into an animation, which is displayed atop the contraption (vimeo video of the animation available here).
The mechanism, which ensconces the yeast within an artificial atmosphere, is essential to the bioart:
"The operation of the machine is necessary for the visibility of the animation. The refrigeration slows down the transformation of the yeast images. One day Bioscience will create machines just as mechanics and the computer code have done. The boundaries between living organisms and machines will soon fade."
Czjzek lets us look beneath the hood of the animating mechanisms, a vantage point less afforded by other wetware machines.
