I think both your submissions are great and I would ask to see some more variations! Maybe go with images on the cube of a mobile phone, tablet, web? Can you think of any cool way to use a "3" as in to the power of 3?
LOVE the new designs! A few comments: - The "phone" image you are using is old.. no keypads/antennaes anymore.. Can you make it a smartphone? - The globe is to represent the internet I am guessing? Put that on the top please - switch the top image of a monitor to look more like a tablet and put on the side.
Last one... Can you make one where the logo is to the left and the name is stacked next to it with "Cubed" on top and "Video" below.
