ThinkGeek has two shirts which are highly related: one features a drumset: http://www.thinkgeek.com/tshirts-apparel/interactive/ac0b/ http://www.thinkgeek.com/tshirts-apparel/interactive/ac0b/ and the other has a guitar you can strum: http://www.thinkgeek.com/tshirts-apparel/interactive/c498/ http://www.thinkgeek.com/tshirts-apparel/interactive/c498/ The negative part about them is that the gear is not extrudes a little bit from the shirt itself.
