I got a few questions on how to do the project presentation.

I want 5-10 minutes of prepared showcase on what is interesting in your project.
The audience is programmers so you can be heavy on the technical details.
You can show code but keep it short and interesting!

Example:
* Tell us about your project vision
* Quick demo, not all tests, but show us it works and is cool
* Short anecdote on something code related.

Its OK for online-students to record a short video, preferably uploaded to youtube
