You like wave dynamics, right? And things simulated in web browsers, right? Well, here's an online simulation of a ripple tank, which I've been playing with for twenty minutes and which I fully expect will keep me busy until lunch. [via]
This is a simulation of a ripple tank. It demonstrates waves in two dimensions, including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, phased arrays, and the Doppler effect.
To get started with the applet, just go through the items in the Example menu in the upper right. You can also draw on the screen with the mouse. The predefined setups are just starting points; you can modify the sources and walls as you desire.
