That is a nice demo! My wife is teaching optics right now, this looks like something she could have her students explore with to get intuition for what happens in different situations.
This is fun, though I wish there was an option for white light - and a traditional prism!
It would be really nice if there was some text that mentioned you need to have WebGL enabled if it's not. And it might be nice if there were instructions or a description of what we were seeing.
Other than that, it looks really nice!
It reminds me of zen photon garden : http://zenphoton.com/ (which doesn't have lens or fiber-optic, but is very pretty).
This is pretty awesome stuff! I'd love to tinker with it and it sounds like a few others would like to as well. Do you have any plans to open source this?
Best part: Chrome lets you right-click/Save As... to download a snapshot of these beautiful simulations.
Human eye with cornea, iris and lens and would be a nice addition for physiology students! :)
Nice. I wish I could add and arrange my own lens elements though!
