this looks so simple but this took days to make. the snakes are designed by me, so are the animations. the top snake uses an up-down-up or an down-up-down motions to create more realistic and defined motions, while the bottom one only will use 1 curve for each of them, making the movement much more smooth. their bodies are warped rectangles, and the heads are 2 warped circles and a stretched and warped line that wraps around the circles and creates a mouth. the eyes are of course a small vertical line.
read the instructions for how this was made and how it works, and below this text for some information. ----------- there is only 1 gallery image so far, but it will have more images soon. at the start press "stop and show buttons" if the buttons dont show up.
