Both videos were very informative; the short one with music reminded me of scenes from the movie "What the Bleep Do We Know". The animation was fantastic, and it always helps to have a visual to go along with such complicated information. I really enjoyed the cargo vessels that were moving along the tracks ofmicrotubules because that was not how I would have pictured it happening if I had only heard the narration. The lipid rafts on the outer leaflet of the lipidbilayer were also very interesting looking. The videos were a great introduction into the tiny world of molecular machines, and I find it incredible that all of these processes can occur. All in all, the videos were not only educational, but also very intriguing thanks to amazinganimation.
