I just read about an experimental storefront from Amazon called WindowShop. It takes exploratory search to its extreme, not providing users with any means to search or navigate beyond scrolling and zooming. Here’s a screenshot, though you need to go the site to get the full immersive experience.
I’m usually a fan of exploratory search interfaces, but I confess I’m underwhelmed. The interface has been compared to the Borders Magic Shelf, but I think Borders achieves a much better balance of serendipity and user control. Curious to hear what folks here think.
