Random shot #3 reminds me of San Luis Obispo's "Bubble Gum Alley" as it might have been in the virgin state before... well, before someone saved their gum from parking it under the movie house seat. I hope this one has a better fate -- maybe modern light sculptures.
Wow, that's a lot of DNA right there !
I looked at pic before reading your description as its so interesting. I liked it but couldn't figure out just what was what.
I guess one could say that's just a little "tacky", ha ha.
