"Rock On!"

Ah, here's a good one. Customer and Gizmo user Colby Hearn emails to say:

I'm a college student taking Calculus I for the first time. Your ShockWave explanation of the Unit Circle just saved the day!

Go you, rock on!

As Deiter was fond of saying on the SNL skit Sprockets: "Now's the time we dance!"

Thanks, Colby!
