This is a HDMI dongle which can mirror the screen from user's phone/pad to TV screen via WiFi.

A tilt squre cutting pattern & texture was the main element on this design.

As known by people, many similar HDMI dongle have a HDMI connector which means the dongle must be plugged into TV when using, but this condition causes a bad look when your TV has a extra device be plugged on the TV itself, so I believe with a HDMI cable to connect with TV and let this dongle looks like a beautiful piece stayed on the table with TV may looks much elegant than what the condition I said above.
