Every generation has worked to make music portable. I am always on the hunt for old record players that run on batteries, perfect for taking to the lake for picnics. And the 80's had the boombox-on-shoulder thing down. So it is only logical that we'd get some portable speakers for our iPod generation as well.
Check out these stylish numbers, or "BoomCases," made by Sacramento-based sound wizard Dominic "Si-Mo." He embeds 30-, 50- and 200-watt speaker systems into awesomely vintage found luggage, and says that the sound from these babies could power an entire houseparty, which means bringing the tunes to your next picnic will be ... a picnic.
If you are someone who is handy with tools and things with wires, you may be able to make your own. Otherwise, prices for the BoomCase start at $250 for a plug-in, or $300 for a battery/plug-in case (though most look to have sold for closer to $400).
