here's my second entry, its a High Def Micro Beamer!
here are the specs:
Full HD support
0 dB by using coolingfins with 5 heatpipes
hope it comes out whithin 10 years!!
to compare the size think about that the HDMI plug is about 16 mm
(makes the diameter about 2cm to 2,5cm)
(correct me if im wrong, sizes from the net)
