A single piece

Nothing spectacular today, probably as a result of lethargy.

Two dumps today

More weird shapes. Wouldn't say they were calligraphic - the second dump, in particular, looked like Auntie Anne's pretzels twisted out of shape.

Strange shapes

Was that an odd-looking Y or was it some kind of mathematical symbol?

Increased output

But not much of a calligraphy today as the bulk of the dump sank to the bottom.
