Help. ;(

Hi there. As we all know, Christmas is coming up and although giving people presents via. their list, me and my mother are very much into surprises. I have a brother, autistic, age of 17, one month away from his license, loves gaming (Currently LoL), He used to make youtube videos and loves anything technological. Bbut be aware, autism can cause many things, and one of such is not liking change. So although I appreciate your suggestions, telling me to buy him a rubber duck probably won't be helpful. We have a few spare hundred dollars, but nothing over the top. He is an author and likes writing. Do you guys have any cool computer equipment, or anything. Are you somewhat the same personality as my brother and want to share what you got? Let me know below!

Forgot to add - He is into fitness, and is home schooled, so has no friends. He is an author and enjoys writing. This also means he doesn't need money. So it needs to be an entertainment/enjoyment prezzie.
