Step 8: Test the "Display"
Now it's time to get a sense of how your LED Art will look, and make any adjustments or alterations. Dim the lights, put the switch on the case in the on position, and hold the frame up to the LED/case assembly, so that it projects onto the back of the frame.
Take a look at the front of the piece, and see how the colors and patterns change over time. You can adjust how your piece looks by gently repositioning the LEDs.
