Some great toons.
I specially loved Mathrim's 'Stars'.
I personally don't feel it worth my time in the other ones to find the hidden clips. Don't know if that's a shame or not - you obviously considered them not worthy of the main feature.
In any case, this too was an enjoyable watch and I really liked the opening effect with the letters reversing the noise.
Although the shorts weren't as good as #3, I preferred the presentation of this one.
