If you used Google today, you will have noticed the “l” looks a little different. In fact, it looks like a pair of legs — those bright orange legs belonging to Big Bird. The “doodle” celebrates the fact that Sesame Street is 40 this month.

I’ve blogged before about how much I have enjoyed Sesame Street over the years, and how its writers rule at clever word play, especially in the songs. A number of them are found in the 50 best Sesame Street moments.

And I have to give Google’s graphic designers props, too. They do the most clever and engaging things with a seemingly static logo!

Update: the doodles went on all week with different characters. My favourite: Cookie Monster’s googly eyes as the OO!
