Open Thread: Light and Shadow

I feel that there should be a distinct word for this phenomenon since "caustic" is way to general.  There's a quality to the shapes created by light through clear waves that ought to have a name.

And sorry for having this a day late this week too.


Friday Saturday Recommendations!  What have you been reading/writing/listening to/playing/watching lately?  Shamelessly self-promote or boost the signal on something you think we should know about - the weekend’s ahead of us, so give us something new to explore!

And, like on all threads: please remember to use the "post new comment" feature rather than the "reply" feature, even when directly replying to someone else!
