Green Lantern power ring

From MAKE blog via BoingBoing: How to make a Green Lantern ring

Now, when I came across this headline, I almost blew my warp core, because any comics fanboy worth his salt knows that the Green Lantern power ring is THE ultimate wish-fulfilment power-tool. Whatever you can imagine and will into existence becomes real, if slightly emerald-tinted, which leads to the awesome vengeful imagery of giant green chainsaws gutting the punk jerkwads what stoled your lunch money. Sadly, this is just a how-to for casting your own fake GL power ring, so there will be no corps of shamrock-shaded shock troops taking to the skies this halloween (alas).
