I think this could be a very useful tool, easy to use and the results can be very inspiring. Especialy if this would be available in any design tool.
I think there is a problem with it on Safari, doesn't seem to work.
This is a nice little tool for anyone who has anything to do with brand building or design. Even if you're "only" looking for a colour pallette you can use in a presentation.. nice that it takes the manual work out of creating an initial colour palette. The interface looks nice too!
