These simple sketches were made using these magic tools here, which I just found this morning on a past post on Geninne's blog. With a little exploration, I quickly found the line options and color wheel but not yet the eraser. :) You, too, can take a moment to brighten your morning!
Note: The linked Mr. Doob tool page may look blank at first, but you'll see the short but sweet tool bar at the top. Just click on things and play around with it like I did. :)
