Some demo appear interesting to me this year:

• Matrix LED Unit
• FuSA2 Touch Display
• 360-degree Autostereoscopic Display (It’s Autostereo! Definitely take a look at it!)
• Beyond the Surface (from Taiwan!)
• Head-mounted Photometric Stereo (This reminds me what has been done in ICT Graphics Lab led by Paul Debevec)
• Touch Light Through the Leaves (Anything more weird and abstract than this one?)
• QuintPixel (HDR Display?)
• Acroban the Humanoid (Much more interesting and cute than robots developed by CMU)
