The key phrase here is **less terrible**, as opposed to **good**.
Right now if the mandala gets too big for the page, it will just overflow and the remainder won't be visible (not even via scrolling). This is intentional, though, as per @ninapaley's suggestion:
> I'm hoping you can change the way the image keeps resizing its canvas, and keeps justifying left.

I'm not super happy with this CSS, it doesn't feel terribly maintainable. Ah well, maybe we can improve it later.
