While I do not know exactly what I want to do for my final project, I am leaning in the direction of something to do with AR. I was thinking of using the P5 dimensions library that i found last week to slightly tweak the 3d space my camera sees and make a sort of existential overlay. this would involve the use of the DOM library as well as the video library for some aspects. 
snapchat sort of does this with there filters an I want to give it a try.
