Over the years, we’ve used what seems to be all manner of tools to collaborate between designers, developers, and the pesky client. Atomic.io (from the video) looks to have some firm solutions, and some features that you just go – yep, need em – didn’t know I needed them – but I do. The splash page itself is simple, except for the cool animated svg at the top that gets the “future of design” point across to potential users.
