Icebergs is a webapp that lets you drag text, images, web ages, upload and save files, make and organize notes, and more.
Sounds familiar? My own Task Information Collections (TIC):
TIC is not so slick as Icebergs and it does not store information to the cloud (yet). And while Icebergs visualises items in a grid TIC does it on a free spatial plane. Nevertheless, a lot of ideas behind TIC have been implemented in Icebergs. I feel flattered :)!
