I have recently used the ViewComm iSpace 2 portable 360 degree projector when I have been out and about with clients, and I received very good feedback on its futuristic design. It is compact and easy to use — and it will run on batteries.
Newly launched on Kickstarter this week, the projector has a circular body on a tripod with an adjustable angle. It’s reminiscent of an upside-down Starship Enterprise, and that is cool enough. But the iSpace 2 has some other neat features too.
