Gene Expression Jam Session will produce the genes you need to do it, enclose them in a nifty virus-shell vector for quick delivery to your DNA, and shoot 'em right into your arm for fast-acting fun! Once you're sick of your newly engineered appearance, you can buy a plug-in that reverses the effects of your newly added genes or adds extra genes to make you look even wilder!
And don't get me started on the consumer nanotech revolution. You haven't truly lived until you've turned your pet goldfish into a golf ball. *
