'SyncSpace lets people express and explore visual ideas together, wherever you are. It is a zoomable drawing space that can be shared in real time over the net. It is a shared whiteboard plus a whole lot more. ∞ DEEP ZOOMING Sketch out your ideas in a nearly limitless, zoomable drawing space. Never again be limited by the size of the canvas or the amount of space remaining in an existing sketch. You can always zoom in to add detail or zoom out to add context to a drawing. With SyncSpace's zooming, handwriting on a 10" screen actually becomes feasible. ∞ SKETCH TOGETHER SyncSpace drawings can be updated by anyone who also has SyncSpace, anywhere on the Internet. You can invite others to collaborate on sketches by sending a link via iMessage or email.
