Google Wave is a new tool for communication and collaboration on the web, coming later this year. A "wave" is equal parts conversation and document, where people can communicate and work together with richly formatted text, photos, videos, maps, and more. In Google Wave you create a wave and add people to it. Everyone on your wave can use richly formatted text, photos, gadgets, and even feeds from other sources on the web. They can insert a reply or edit the wave directly. It's concurrent rich-text editing, where you see on your screen nearly instantly what your fellow collaborators are typing in your wave. That means Google Wave is just as well suited for quick messages as for persistent content — it allows for both collaboration and communication. You can also use "playback" to rewind the wave and see how it evolved.

CatchBob is an experimental platform to elicit collaborative behavior of people working together on a mobile activity. Running on a mobile device (iPAQ, TabletPc), it's a collaborative hunt in which groups of three persons have to find and circle a virtual object on our campus.
