I've been experimenting with solving the wave equation numerically for the past few days. I wrote a Java program from scratch to do this, and here's what's come of it. I've decided not to put the source on GitHub since it's kind of terrible, but the code is somewhat similar to the double-slit experiment demo on my website if you're interested in building a similar program.
