For my final project my plan is to have it to be open sourced. Instead of me doing demo for others to watch I would like people to interact with it, draw their own discs and create their own musics.
Once I develop the App for the music player for the next spiral I will build a webiste for the project, with all the info of the design and software and download links so anyone can produce the disc player him/herself. I may also start a campaign for the project after I have a polished pototype. I may post it on crowdfunding platform like kickstarter to gain funding and further build the project into a product.
Here is a list of licenses from choosealicense.com for my own reference.
I encourage people to reproduce my project on their own, distribute to it or further develop it. Commercial use is welcomed too.
