The profile picture is a set of Japanese wooden robots that blow my mind. Check 'em out withthis link.
I did some work on a series of book-cover palettes, as well as palettes based on portraits of some of my favorite authors. When I'm making these palettes, I am very careful about which colors I choose and how they work aesthetically with each other. I also try to start with books that I feel have strong cover artwork in the first place. I am a book-lover, and I see no reason why we can't judge a book by its cover.
I use this space now more as a springboard to play with color palettes for web and design projects I'm working on.
