I got this idea from NikonRob, who did a similar picture. Mine's a little bit more zoomed in than his, but basically the same concept. Mainly trying it out as a texture shot. I had entertained the idea of shooting them, but as shiny little seeds, I was thinking of them as not all that interesting, not really considering them as a collective whole and as a texture.
