"Picolio" is actually two words, well ok technically it's a word and half. I came up with the name because this is a picture gallery full of a variety of pictures that do and don't relate to each other. Much like "Left Over Stew" that is loaded with a variety of foods all unique but together creating a single meal. The pictures may not fully relate to each other but they all involve happenings around me.
Pic: The short version of "Picture". Internet residents just love to chop words into pieces :-)
Olio: Dictionary.com defines it best:
o·li·o ( P ) Pronunciation Key (l-) n. pl. o·li·os
A heavily spiced stew of meat, vegetables, and chickpeas.
(a) A mixture or medley; a hodgepodge.
(b) A collection of various artistic or literary works or musical pieces; a miscellany.
Vaudeville or musical entertainment presented between the acts of a burlesque or minstrel show
The domain name being available had a lot to do with this choice as well :-).
