This is a simple simulation of blades of grass. It uses the sine function offsets and rotations to make this effect. My "Blade of grass" project http://scratch.mit.edu/projects/AddZero/822057 is easier to edit and understand if you want to download and see how it works. Let me know if you have questions. 1/1/10 in top viewed. Thanks! It now has color option and can have a negitive lighten value.
