Hi bees!

I'm sponsoring a foster child for Christmas and am looking for gift ideas for him. All I know is that he's 16 and is into acting, Broadway musicals, and computer science. He has a short list of things he wants or needs, but I'll still have a $50-75 window to get him a couple of items after I buy what's on his list.

Does anyone have any suggestions on Broadway musical or computer science-related gifts I could get him? I could only think of a book about musicals (not sure that would be "cool" to a teenager?) or a Raspberry Pi starter kit (https://amzn.to/37wPeJo).

Any and all suggestions are welcomed!
