I tried various options for product icons using view finders as metaphors, geometric shapes, line drawings and monograms.

I tried one splash screen using stock photography and the monogram icons. Ultimately, photography would have been too costly.
I sketched another option with a marker than brought it into Adobe Illustrator for a more woodsy theme. This was very well received, but ultimately felt like to much of a change. I later re-purposed the theme for our pattern library.
