Big Brother gift for a ten year old?

Hi! So there are ten years between this baby and my older son and I would like to get my oldest a Big Brother gift but I have no idea what to do? He's a bit old for the traditional Big Brother gifts that I have read about and I'd like to get him something meaningful. He picked a "Little Brother" one piece outfit for the babies going home outfit which I thought was so sweet and I'd like to get him something special too. Any suggestions very much appreciated!!!
