Almost every single Fry's had a different theme, Fremont, CA's theme was the cultivation of electricity, it had a fully functional tesla coil (\~10 feet tall) that ran every 30 minutes or so.

Pheonix, AZ had a Mayan/Aztec theme.

Also, fun fact, Fry's electronics founders were related to the founders of Fry's grocery stores. The logos are even quite similar.

Edit: added "Almost". Pretty sure they all had unique themes up until a certain point in their expansion.

The Fry's north of Indianapolis must have had the theme of "empty."   The last time I went in there I couldn't find a salesperson anywhere. It was a ghost town.
