Citric acid
Hello, fellow microscopists! I just joined your wonderful forum and decided to make an introductory post showing some citric acid crystals. I used a very simple (yet seemingly effective) polarizer made from a tetris game LCD screen.

bromodomain,
Welcome aboard!
Even though you have treated us to citric acid crystals, it appears from the first image that you have managed to maintain the "snowflake" theme that has appeared on the forum in several places recently.
The LCD screen polarizers do seem to polarize well. Are you using it for both polarizing positions? I don't think they are optically great to use in the image path, although fine under the subject as the first polarizer.

I've used two LCD screen plaques at 90 degrees, one placed in the filter holder of the condenser and the second one is above the objective turret. They're most definitely not great but considering how simple (and affordable 
) they are I'm delighted with the results.
My equipment is fairly modest. I'm using a Carl Zeiss standard KF microscope and a Sony DSC-W120 7.2mp camera.
