This is an excellent effect Merek. To say nothing of your nice sharp images.

Very colourful, but what is it? The name tells me it is normally yellow?

My refs have it as a Desmid alga, e.g. http://starcentral.mbl.edu/microscope/p ... geid=25557.

Nice image -- sharp and colorful!

This is the desmid Xanthidium antilopeum, the most common of Xanthidium. There are many var. of this desmid, this could be var. laeve. Xanthidium antilopeum, cristatum and octocorne I find a lot in samples of De Haeck Zegveld in The Netherlands. And Cyclops, they are allways green, not yellow. Some desmids are very interesting to see in polarized light. Great picture.

I was wondering what happened on that one. That ID you had posted seemed rather out of character!

HAHA, I finally figured out, I had a second window open with Franciscos testate amoeba in it. Not even sure how it happened, unless it was the leftover window from the YouTube link.
