What would you do with 1000 22ohm SIP resistor-networks for $2?

The best I've got is a physical implementation of that old Google Challenge: You've a giant matrix of resistors, what's the resistance between two points? Surely there's more can be done. Ideas? Buy 'em up!
(edit: I thought there were 4 per package, actually there's 5!)

I used some resistor networks in my LED Cube ( http://hackaday.io/project/2167-iot-rgb-led-cube-4x4x4-with-bluetooth ). Putting them in sockets allows you to adapt the resistors of multiple LEDs later - usually you start with oversized resistors for the cube while building it and programming the software (so your LEDs don't burn out). Once you are certain everything works without hanging you can undersize the resistors and get a brighter cube since most LEDs allow higher currents for a short period of time. Especially useful when multiplexing.

three or so in series to drive each LED... Could make for some groovy structural effects in 3D electronics like LED cubes. Could even cross-over a few, here and there, soldering different networks to each other on resistors that otherwise don't go anywhere, just for structure-sake. A literal bridge made of resistor-networks!

$10 minimum? Guess I'll need to get 5000 then :P
Are you sure? yes | no
Hahaha! That'd be 25000 resistors!

I've heard about people using files to get different resistor values. But I'm not sure how much you could change them.
A resistor based heater, chain them in parallel to drop the resistance and add some electricity.
make a board for battleship, where you can place your resistor battle ship and an adc scanning the matrix can check where your boats are.
Could also work as a locking mechanism, where you have to place the resistors in the right position to get a certain resistance value to open a door or something.
Resistors would be so much cooler, if they would glow like LEDs.

hah! Battleship!

Home-rolled DACs. The resistance is a little too small, but with 4000, who even cares, you could do a ladder with 20 packages of them

Good call! They're more than just 5-gang 22-ohm network-resistors. They're 110ohm resistors with multiple-taps :)
