Phantom Research Foundation is a collection of artists, designers, and musicians. That’s all well and good, but they have a beautiful Flash site. I’d go as far to say that it has the best navigation I’ve ever seen. Stunning. The site is designed by Gizma, which also has a great little Flash site. Small and simple, but great feedback and interaction.
John Friksson has a pretty nice portfolio site, notable for its retro use of horizontal scrolling. I feel like it is 1998 again. The work is pretty good too.
Stockholm Design Lab is a Swedish design firm with a pretty nice, but simple, site. No big deal I thought, until I noticed that they did the identity for SAS airlines (including their aircraft exterior design), packaging for IKEA, and branding work for Sony Ericsson. In short, some pretty impressive clients. I’m very jealous.
