The scientists at Living Ink Technologies in Denver Colorado have just begun a Kickstarter campaign promoting a greeting card that could revolutionize how ink is made. Their greeting card and art kits use living algae to create a time-lapse message or image that grows with exposure to sunlight.
Using algae for ink is possibly the most novel applications I have heard of in the algae industry and one of the most feasible. There would be significant positive benefits to the environment by replacing traditional ink with an algae based ink, and Living Ink Technologies is proposing to do just that.
Checkout and support their Kickstarter right now and you will get to make your own living algae art and be one of the first people to use the ink of the future.
