We've had a lot of successful student projects as part of Google's Summer of Code in previous years -- we hope to inspire you to work with us and (hopefully) add your own success.
all of these tasks, you'll probably need to already be comfortable with a basic level of C++. Some of the tasks might need more specialised knowledge (for example, working with ResidualVM may need you to understand some OpenGL and 3D math).
Most importantly, we'd like you to join our community. There are many previous GSoC participants who are still involved in our project, and whether or not you participate as part of Summer of Code, we'd love for you to get involved too.
You should come to our [[IRC Channel]] and introduce yourself! We're friendly, and it's often the easiest way to ask questions about the tasks and the code in general. The channel is the main form of everyday communication for the project, and there will almost always be developers there who can discuss your project ideas, answer questions and help out.
