I just stumbled across the work of German amateur(?!) photographer Markus Reugels via this article in the 'Design' section of the Fast Company website. Reugels has developed a speciality in producing intricate 'sculptures' from the interactions of water droplets frozen by a high-speed flash. The results are often extraordinarily beautiful - and leave you wondering how on earth he did that.
You can check out more of his work in articles here, here, and here, and in extensive online galleries here and here. And of course, it's worth taking a look at his own website as well, where he posts a link to this (English subtitled) 'behind the scenes' film on Youtube - which leaves the sense of awe undiminished even after he's told you in detail how he did it.
