Cleanfit Systems is a consultant firm that provides services to cleanroom managers at large semiconductor fabs.

The principals at CleanFit wanted a logo that emphasized the boundary that a cleanroom locker room represents.

To start, I found a photo of blood cells, and darkened it with a filter. I used a blue sky for the top photo, and a photo of light reflecting off a pool for the boundary. The sans-serif font underscores a sense of cleanliness.
