It certainly is nice to see someone using a different approach in the algae industry. Living Ink Technologies of Fort Collins Colorado is a new startup in 2014 and are using their experience with algae to do something completely different, create a photosynthesizing greeting card. The company is currently in its development stage and has several card prototypes on its website.
I really like the idea behind these cards. The cards are stamped or painted with various strains of algae which can lead to different colors and different rates of growth. So a colorful living message and image can be revealed through time.
The founders of LIT are Scott Fulbright and Steve Albers, both graduate students at Colorado State University are researching various components of algal technology, including biofuel and pigment production. I wish these guys the best with their venture and I can't wait to order my first Dunaliella salina based greeting card.
