Color-change glasses let you coordinate your eyewear every day
You change your clothes every day to suit your mood, so why not
your glasses? Sure, glasses are pretty expensive, so you're not
going to own a bunch of different pairs, but that's not what I'm
advocating. Why not have one pair of glasses that can change to
go with any outfit?  The RbG Rainbow Glasses are hollow plastic
frames that you can fill with any color of water-based ink that
you want. You can empty them out at the end of each day and
refill them in the morning, or just leave them empty for a clear
look. Too messy for you? Well, just wait for the next version,
full of LED lights that you can change on the fly. We hope.  Via
