Fun idea: this gadget can turn your smartwatch into a smartphone

Shell is a startup that wishes to change that. The flagship product — due to start Indiegogo funding near the end of January — is the Shell independent smartwatch. It's a rather bulky timepiece that holds expandable “wings”. Stretch them out and they will act as antennas and microphone / earpiece combo. It even has a camera on one of them! It comes in two variations — round-shaped or square-shaped, with the latter being considered as the more rugged edition.
