I just started playing around with Blender and this is my first try with boids. I should not have used a checkerboard ground - makes it kind of hard to see the particles. Maybe some camera movement would have been nice, too.
I am not going to improve the animation, because it was just some 'quick' messing around with Blender and not done to achieve this.
The animation took 5 hours to render, because I chose too high quality settings (and there were 2,000 frames rendered - might have influenced it, too...). But in the end it did not matter, because I went to sleep after starting the process.
