Electronic geeks...help with flashwear shirt

I scored a Flashwearshirt for $1.99 minus the battery pack.

is there a way I can get my shirt to be fantastically geeky from …say…radio shack power pack thing?

Is it a loss?

I answered my own question by surfing the website a little farther down.

So.
Never mind.

It says the power is 4 AAA batteries. Buy a battery holder that holds 4 AAA batteries or 4 AA batteries and put the correct end on the pack to connect to the shirt connector.
