My experience: just make sure you're already confident implementing it on a CPU first. GPU coding is hard enough without actual difficulty.

If you want to cover "all the details that [you] have learned", it'll help to state what you learned. Also, what exercises you've done already - what level are you at?

1. a shadertoy (web, desktop or app) for GPU programming, with comveniences for image processing. That deals with all the BS boilerplate you learnt, from a general point of view, and will be useful.

2. Fluid simulation (but, there's a lot of non-GPU maths to understand).
