Is this strictly a knitted pattern or can it be crocheted?

What's a Pi shawl?

A circular shawl that starts in the center, is knitted "in the
round" (flat, but on circular needles!).

The idea is simply that for every inch wider the shawl is,
it has to be 3.14 (pi) inches more around in order to lie flat.
However, since knitting is flexible and stretchy, and lace is
more so, you don't have to increase 3.14 stitches for every
half inch of knitting (one half inch on each side of the circle
adds to make one inch increased diameter). You can knit your
lace pattern evenly for, say, four inches and then add 4 pi
stitches spaced evenly around the shawl: that would be
4(3.14)=12.56 stitches (call it 12 and add 13 after the next
four inches). EZ liked to do a few rounds of plain knitting
between lace motifs and place her increases there, but
sometimes they can be worked into the lace pattern itself.

So you could probably do it in crochet, especially if you use
one of the fancier stitches that make a more flexible fabric.
Something with treble crochets ought to work.
