Hello! I'm writing my bachelor thesis in one and a half year and I can suggest my own topic, so I thought that it would be great to go with rust and wasm, because my specialty is related to IT and multimedia studies. I want to prepare now and make something really awesome... 
. so my question is what options do I have, what can I build?
How about trying to get a Rust piston game working in wasm? That should touch a lot of different technologies and might reveal areas where Rust could be better suited for wasm-based game development.
