Is there a mac plugin like this one?

[sharisiggies]

Hi... hope someone can help.. on the pc there is a filter by xero called Fritillary. I have contacted the creator and he said he won't be making it for mac. Is there something else that can do the same stuff under a different name? I am using photoshop cs3

you can see it at http://www.xero-graphics.co.uk/set4/fritillary.htm
It does Granularity, Aggression, Tesselation and Variation.

thanks for any help
