One of Franktuary’s favorite websites is that of Good Night, States.
Franktuary particularly likes how the web interface mimics the appearance of a synthesizer. All the knobs and keys serve as links to different pages on the site. Franktuary is now thinking about changing its website to resemble its cash register. It would look something like this. A BIG improvement, yes?
Your customer’s vantage point is your store. Only you see the register. So not sure how well your customers would relate to such a website. Just my 2 cents.
