Open Thread: Caustics

The glass gallon jug was free to good home.  Its shadow and caustics are seen here outside of the building where I found it.  The sun was bright, the wind was strong.  The dark shadow that goes out of the right side of the picture is from note saying it was free, it's being blown straight up here.

Friday 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!

[Added:] Sorry about initially publishing this without a name, and as a political season reminder, please take any stuff on the election to The Slacktiverse.  In fact, I've just made an open thread just for political stuff over there.

The platform there is kind of overly cautious when it comes to new faces so your comment might not show up right away if it's your first time posting there, but I'll make sure that it's told your not an evil spambot once you've made your first post.
