The ultimate iPhone accessory

Finally available after months of hype, Lapka's actually four separate, artfully designed, sensor-packed dongles that individually hook up to an iDevice to "measure, collect, and analyze the hidden qualities of your surroundings". They can read ambient humidity, radiation levels, electromagnetic frequencies (presumably other than the ones from your iDevice currently giving you mad tumors), and, most intriguingly, whether a piece of raw food is organic, achieved by measuring nitrate levels left behind by synthetic fertilizers.
