Okay, I hate gushy cross-posts as much as the next person, but this site is really cool, promise promise promise...
The New Zealand Book Council has gone to a lot of time and trouble to create a web site that lets you read novels at work on your computer screen, but make it look as if you're working. From the phony Windows XP login to the phony Windows XP desktop (hint: you have to double-click to launch stuff, just like in real Windows), the site looks like a regular office screen. All of the novels are formatted to look like PowerPoint business presentations — someone walking by would think you were reviewing a service or product by a third party.
I think it's freaking brilliant, so long as you don't work somewhere that (ahem) tracks IP addresses.
Cross-post disclaimer: I found out about this from Beatty's Book Blog.
