What Is the Best SHM and Circular Motion Applet for Visual Learning?

Homework Statement

I'm looking for a good SHM / Circular Motion applet.

The Attempt at a Solution

My professor had shown us an applet that had a hanging mass on a spring and a circle in the same applet... Really helped us understand the inter-relationship between SHM and uniform circular motion.

Anybody know of a good applet for this so I can try it at home?

Also, is it true that period (T) depends only on the mass of the hanging object (m) and the spring's constant (k)? In other words, changing the amplitude alone doesn't affect the period, right?

Yes, the period of a simple harmonic oscillator depends only on the mass of the object and the spring's constant. Changing the amplitude does not affect the period. A good applet for this can be found at http://www.walter-fendt.de/ph14e/shmapplet.htm.
