With nothing to do with any gay movement (as far as I know), the rainbow technology is a method developed by Sainul Abideen (24 year old Indian engineering student) that lets you encode data into shapes and colours to print them in a sheet of paper.

You’ll be thinking by now: You’re a nerd! Why is that so interesting? Well, just think about that... you’ll be able to encode 256GB of information in an A4 paper, that’s more than 54 DVDs in a recyclable support... isn’t that amazing?!

Of course we won’t be carrying around A4 paper sheets (that was just an example) but the possible application is including a small scanner in our computers and use “Rainbow Cards” a SIM sized card with 5GB of storage capacity.

These Rainbow cards will be way cheaper to produce than a CD or DVD, and they would be biodegradable and recyclable so we’d get rid of a huge amount of e-waste.

So think about it… low cost biodegradable storage devices… a dream come true!

Unfortunately, I think we will have to wait many years until we get this technology in our computers, so we’ll have to be patient!!
