Intern Motion 2 from eric armstrong on Vimeo.
these are some concepts i whipped up for a motion reel at Juxt Interactive - i didn't design the logos but everything else was me... my favorite part is in the second one right before the energy beam shoots out - all the particles come to a gradual stop and then take off when the beam fires: i don't the vimeo does frame by frame so you may have to look close
