its pretty simple, its the same movement you use to get just about anything your not directly connected to off the ground. first, load up you legs, and crouch down. explode down with you back foot, and as the board comes up, rol your ankle and slide it forward. then land. but like anything, it takes practice to get comfortable with it.
i looked on google but all i could find was 3D Animation porn-sxmarty6
well start by learning it standing still and holding onto something pop down hard wiht your back foot so that it makes a crack snap or pop noise...rice crispies style then turn your front footon its side and slide it forward, up the deck when you can do it fine holding onto something try it standing without something then go to movie...and by the way bud you part of the ns skateboard cult? ill add you in and you can ask your questions there
also, when you have the ollie down, kickflips are pretty much the same thing as an ollie.except when you slide your foot forward, move it to the left (or right if you are goofy) and heel flips are just the opposite. but i recommend learning shuv-its too. really simple, just kinda jump forward and pop your skate i a 180.
aaah think of it this way: you are basicly trying to pop your tail, then touch your front wheels to the ground. THat's how I learned anyway. it is weeeyadd....also learn to carve and do bertleman slides and drop in on small ramps because I think it is funny how I know kids who can kickflip lipslide but can't even drop in a vert ramp or like a 9 foot halfpipe.
