Kinopio is a visual thinking tool that can be used for things like brainstorming, organizing thoughts, mood-boards, planning, basically for figuring stuff out (by yourself or collaboratively).
I've been building it for the last year after leaving my job as the co-creator of Glitch (http://pketh.org/hello-kinopio).
There's no sign up required to use it, let me know what you think,
thx!
