Hurry! It's not too late to miss the giant tortoise race at Zoopolis 500!

If it is indeed too late, you could zip off to Leipzig for the Gothic Wave festival this weekend. It's not a tortoise race, but hey.

Alternatively, you could come to my hometown tomorrow and take part in the biggest Mentos & Diet Coke demonstration ever! (Thanks, Nathan!)

The past: Roman towns were aligned according to the stars.

The present: London Remembers catalogs all the odd plaques and memorials about the city.

The future: that Star Trek scanner wand that magically diagnoses your ailments could become a reality! Yes!
