From How-To Geek:

Just because you’re stuck at your desk doesn’t mean you can’t sneak in a little fun. At BuildWithChrome you can slap together virtual LEGO bricks with ease.

The site, a collaboration between Google and LEGO, shows you a massive map of Australia and New Zealand covered in thousands of LEGO base plates. Zoom in, select a base plate, and get building. The block selection is fairly limited (you can work with the kind of blocks you’d find in a generic LEGO brick pack) but it’s still quite a bit of fun.

From Adafruit:

After seeing Ladyada’s Workshop, I started thinking about various ways Adafruit electronics and LEGO bricks could be combined.  I’ve always thought it would be cool to have a minifig scale video display instead of a sticker or printed brick.  So, I decided to give my minifigs a dynamic train schedule.
