i assume with "positionable" you mean led's attached to a lead that you can 
place elsewhere. if you mean to have the position controlled by usb as well, 
that woul make things more complicated, of course.

the cost for that would be around 30 euro in parts. you can save a lot when 
you request the microcontroler as sample from microchip.

you would need a chip, a usb socket, a crystal, two capicators and some 
pinheaders to connect the led's to, all mounted on a perfboard.
if you want to drive more than one led at once (i.e. connect 5 led's to one 
output), you need to add a transistor and two resistors per output. for ten 
outputs, add another 5 euro for the drivers.

you need to buy the parts yourself and send them to me, if you want me to 
build it for you. all you need to include is the postage to send the stuff 
back, plus whatever it is worth to you that i build it for you. thats all.

if thats ok for you, contact me off-list, i send you a partlist then.

greetings,

chris
