If you’re a colour geek, you might find this Colour Cube Kickstarter project interesting:
http://www.kickstarter.com/projects/657220568/swatchmate-color-capturing-cube
It’s a device that allows you to get the colour value of any real-world object.
Kickstarter funding closes in 2 days and it ships in June (or thereabouts).
I’m looking forward to hours of fun when mine arrives – and I can finally find out the exact shade of grey of the Alexander Building on Beaufort St, it’s been driving me nuts!
