"For every day in 2013 San Francisco based artist Klari Reis will be creating art within the confines of plexiglass petri dishes for a project called The Daily Dish, which is a continuation of a project she completed back in 2009. Klari uses layers of reflective epoxy polymer to create colorful and abstract paintings that look like living microorganisms." Via Daily Petri Dish – Honestly WTF
