anniversary help!

Hey ladies! My SO and I have agreed to make each other something for this anniversary. Not because we don't have the money, just because we like the sentimental value, plus we literally have everything we need/want, so neither of us have any ideas whatsoever on what to buy! Do you ladies have any DIY ideas? I went through Pinterest like 50 times and can't seem to find something just right. So any help is well appreciated!
(Details: we've been together for 8 years. I'm a current radiologist, and med student. He works for Ameren [power company]. He loves video games, is very tech savvy, and he plays the drums & guitar (I'm giving these details in hopes it will help someone help me think of something. Normally I'm extremely creative but I'm at a loss here.)
Thank you so much in advance!
