The most obvious comparison that can be observed from these two talks is how new strides are being made in the ability to create highly enriched content in the field of IT. The ties of these two projects to open source is also something to take notice of. The main difference between the two talks was that the commercial dragon game using processing.js is not open source and a person needs to buy and obtain a license to use it. Whereas XB PointStream, is an open source product. Thus Spongelab Interactives wants to earn profit by using open source and Arius3D does not want to sell the software but uses it to create its own 3D PointStream images. Also in the Popcorn.js and Popcorn-Maker presentation by David Seifried, he talked about the features and functionality that the Popcorn.js library can provide to users and how the library allow film makers to better showcase their videos. Besides that both of these projects rely on an open source community to help contribute, test, develop for, and maintain. Both presenters focused on the importance of community in open source projects, the ability for people to give back to the community to keep it healthy, and on how taking part in the community helps raise awareness for these projects which will ultimately create a richer and fuller web experience for everyone.
