In this lesson
Never clear the canvas. Paint a thin veil instead. We build it live in about 11 minutes, then you change it in the Lab until it is yours.
Try this after
Change one number at a time and write down what it did. Most of the good surprises in this course come from the third or fourth change, not the first.
( In this module )
Keep going.
