Actually for this you would need shorter intervals - half a second of 
animation for a whole year is not exactly very useful...

The processing used for generating these looks quite impressive, i first 
wondered how they managed to generate a more or less cloud free image 
from only a month of data - the usual 32day composites contain 
significant cloud cover esp. in tropical regions.  You can find details 
on this and other processing aspects on:

BTW an early test render (using the 2km variant) can be found on:

(physically impossible BTW - notice the lighting combined with the 
january image...)
