About the name

It doesn't have anything to do with my radioactively cute niece. It's taken from the word anacrucis or anacrusis, which means:

n.

1. One or more unstressed syllables at the beginning of a line of verse, before the reckoning of the normal meter begins.

2. Music See upbeat.

[New Latin anacrsis, from Greek anakrousis, beginning of a tune, from anakrouein, to strike up a song : ana-, ana- + krouein, to push.]

Neat, huh?

Here's a visual, if you need it.
