I hope you haven't had lunch today.

The dizzying artistry of Oleg Sherstyachenko borderlines on crazy, but the Russian skyscraper-scaler began doing "stunts" when he was sixteen. 

Now, under the name "Oleg Cricket," he performs stunts on some of the tallest buildings in the world without even so much as a harness. 

That feeling is your palms getting sweaty.
