Ha, I like your wallace better than gromit, cause he can breath in space. I could just sit here for hours and watch this animation, but i won't so 7/8 cause it's very smooth and the moon is excellent.
The moon is made of cheese here and you talking about gravity? So no, no jumping 
haha, great. looks like wallace from wallace and gromit =)
diggin the parallax-scrolling. considering the lower gravity on the moon, should he be more jumping though?
EDIT: now i see, like tomic said it was wallace.
