I was on a gentle long, flat walk when I looked up and saw a hollowed out tree trunk with dead branches sticking out, and for the first time saw how branches extend into a tree trunk! From a leverage perspective, this makes sense, but I just have never thought about there being branch mechanics beyond simple strength of material.

The second picture gives a bit more context for the closeup.

My vacation doesn't start until I get in the ocean, and soon after I did that this year, I came upon this seagrass by the boardwalk, and something about the curve and the lighting and the texture of the seed heads grabbed my attention, so I snapped a few pictures.  We all really liked the way this one came out.
