Drag the dots. Watch the colors mix. OOOooooooh.
It uses the RGB block I made. Just an example of it in action, and to test drawing over the whole canvas. It picks a resolution depending on how fast your computer is, to keep it responsive. (And also now renders sharper then waits if you're not dragging dots. ...And now dots fade when mouse stops.) I started on allowing the user to place many dots, and set the color of each. Look at the stage and balls sprite for the start of that. I'd like the dots to work more like spotlights (color, brightness, size, blend(softness of the edge)... Feel free to play with this!
