Do you love a productivity nerd? Then save them from themselves with some of the most addictive, time-sucking gizmos out there.

This is exactly what it looks like: a four-bladed R/C helicopter with two cameras. You control it with your iPhone, iPad or iPod, which display what the camera sees in first-person view, meaning you can fly it out the window of your house, look around on the roof, and bring it back -- as if you were living inside the space shuttle and you had a repair robot to check the gutters. Yes, the A.R. Drone Parrot turns any well-adjusted adult brain into that of a 10 year old. Did we mention that if you have two of these things and a friend, you can dogfight with lasers? Pew! pew! Price: $300 from Amazon.

Propellerhead Software’s app ReBirth for iPad has one job: to perfectly emulate three epic dance-music-making devices. Inside your iPad now lives Roland’s TB-303, TR-808 and 909 units -- which are bass synth and drum machines, for the uninitiated. Now anyone with a pair of headphones and an iPad can spend hours drinking Monster and composing 808 dance beats while imagining Natalie Portman dancing in a south London club. You can share your tracks on Facebook and Twitter, too. Price: $7 on the iTunes App Store.
