This is a current design study by Siemens Gigaset, created in line with the design concept "Gigaset Design Visions". Relevant future technologies have been implemented in a hole series of concepts.

The picture you see on top shows a Siemens Gigaset "Helium" phone. It's an approach to fill a DECT phone with ECO technology which should be refelected through ecology-minded material & visual appearance.

More "detailed" information about the phone itself as soon as I have this info...;)
