Particle Effects Inspirations

We're moving onto the final stages for coming up with and creating particle effects for my programming class so I dug around the depths of You-tube and elsewhere to find some good references.

I'm looking for various spark effects so I felt these would be some cool videos to look at as refs:

Some really cool sparks!! Look at that thing go!

Explosions, sparks and some good ol' destruction. To be expected though since it's a Bay film.

And just to spice it up, I'd really like to make some cool Sci-fi particles for my boost-pads. 

Here're some cool inspiration videos for that and a quick sketch!
