Eco-friendly mobile phone designed by Formwelt Studio for Siemens

Siemens entrusted Formwelt Studio to design 2 new eco-friendly conceptual mobile phones, one called "Leaf" and the other "Solar". The material used to make the "Leaf" phone mainly consists of recyclable eco-plastics. Its shape resembles that of a lush green leaf with an OLED display screen embedded in its semi-transparent slim body. There are 2 shapes designed for the "Leaf" phone. The only problem I have with the shape above is that due to its curve, although it is light and thin, it is not very convenient to carry. This issue has been resolved in the shape shown below.
