Thanks! I love my glasses too, and they don't make them anymore. So I live in constant fear of breaking them :/
my doubt is the dye (Crystal violet) used for differentiation is organic or inorganic?
That was really sexy bacteria. -fans self- Great photoshop work.
Thanks all for recognizing how super sexy the E coli became through the magic of Photoshop! This weekend I made a ceramic travel mug with painted Staph and E coli (Perhaps the only one of its kind?) Painted fimbria on the E coli...which made them look super duper sexy. Once the mug gets fired, I'll post a photo on the website.
