If you do not call this at the beginning, the default will be 100x100. background(0,0,0); Calling the background function lets you change the color of the entire canvas. Stroke(255,0,0); Calling the stroke function lets you change the current drawing color so that every drawing command called after it will draw using that color. 255,0,0 means red. Point(50,50); Calling the point function will set the pixel at 50,50 to the current stroke color. This code makes a green dot in the center. stroke(0,0,255); point(150,50); This code makes the blue dot on the right. As you can see, this is similar to draw( ) Image Lingo, or those drawing methods in ActionScript.
