E-Rex: moving robotic display

Some time ago, I blogged about Rob-o from LOEIL (laboratoire objet espace intelligence langage, Aix en Provence, france). I recently stumbled across another piece that I found stunning. It's called E-Rex (same naming pattern). E-Rex is basically an interactive installation made of a robotic screen ("Ecran Robot Exploreur" = Robotic Explorer Display) located on a huge mobile "arm" that can be manipulated by spectators using an spherical interface. The E-Rex device can make circular movements and shown videos/3D scenes. What's intriguing is the integration of motion and speed of the display since the video control the rotation of the arm.

Why do I blog this? I quite like the way this piece looks, it's massive and fluid at the same time.
