What should I do for my older brothers 18th birthday?

His birthday is in May, but I want to think ahead of time.

Usually my parents dont do much for him on his birthday. I was thinking that becoming an adult is a big step, and wanted to do something special for him.

What can I do that will be memorable to him, and that he will appreciate!?

Something to keep in mind; I am at a financial disadvantage, so I cant really go on a huge spending spree.
