Caustics and dispersion

!!!This is outdated! We have native dispersion in Corona Renderer now!

Here is a small video on creating caustics and dispersion:

It is based on Borisquezadaa's ideas:

This was not made with intention to be posted in Corona's official YT channel. Why? Because it was done really quickly, off the top of my head, and covers things which are still in experimental stage and will require some manual "cleaning" to look good. But still, there have already been some impressive images created using this technique.

Can you reupload it? Maybe to youtube with the unlisted feature and all caps disclaimer, "this is a trick, not a feature".
