A pretty little book. It brings together several papers on fluid mechanics, where each paper is distinguished by one or more snapshots of fluid flow. Inspiring to the researcher, in much the same way as perhaps hardcopies of VLSI designs are to the chip designer.

But the papers and diagrams here also serve a serious purpose. In fluid mechanics, a lot of qualitative understanding can arise from studying such diagrams. Not the least because sometimes modelling the equations leads to massive sets of numerical results, which might have to be understood visually. And in the book, the diagrams are of actual experimental results, not simulations, but the idea is the same. You often need some diagrams to understand the underlying phenomena.
