I've just started microscopy with a Swift 280. I Took this video of some filamentous algae [youtube]https://www.youtube.com/watch?v=n2BF_5mSdAA[/youtube] Can anyone tell me what the organelles are that are moving so fast, and why are they moving so fast?

Cheers

.
You don't mention the magnification, so it is hard to say. I would go with either speeded-up video or Brownian motion.

Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

It might be contamination from motile bacteria. We often see this kind on motion in our plankton samples after they have aged for a few days. Cytoplasmic streaming of organelles within plant cells tends to be more orderly https://www.youtube.com/watch?v=H4kkQvKsNzw.
