If you’re on an iOS device, today’s Google logo is pretty neat. Simulating the brass-plated portcullises of Captain Nemo’s Nautilus in order to celebrate Jules Verne’s birthday, the logo will read your iPhone or iPad’s accelerometer and slosh around the subaquatic view accordingly.
If you’re on a laptop or a device without an accelerometer, no problem: a handy joystick next to the logo will simulate the effect.
