This blend was created with Blender 2.69
I created it as part of the weekend challenges here:
This is for weekend challenge number 546 with the theme: Vibrant Contrast
To create my image for the challenge, I duplicated the paint can several times, creating a new paint color for each new instance. I then created a group with the cans. Finally, I added a plane and a particle system emitting the group from the vertices.
