Niice.com

"For my work at Institute for the Future we're often trying to distill these nebulous concepts about the future into images and into words that people can understand. It’s really important that we get the visual part down right, but most sites aren’t really great for visual inspiration. … but Niice is this incredible site that shows you really creative imagery and often a lot of original art from artists, which is great because sometimes it can be hard to access the people doing really interesting creative work. Niice is meant, I believe, for designers and for design firms to do premium mood boards. … The great thing about this site is it can make me associate new concepts actually that I hadn’t before. It’s a really neat way to think about the future visually."
