I have posted building instructions so YOU can make your own, if you have the parts! (Actually, the instructions are for an even better version)

Song is "Cataclysmic Clash" by Game Over.
My Chinese water dragon eats a couple crickets then goes through the bathing ritual. Very exciting. Music is Mambo #8 from the Office Space soundtrack.
I was experimenting with trying to make a flat, compact K'nex firing system that could be stacked multiple times when I came up with this success. Four barrels, one trigger for each allow for single-shot or burst-fire. Surprisingly powerful and easy to reload.
A neat gadget built using K'nex and a thread that shoots people as they walk by with a tri-shot spread effect.
Music by the wonderful DJ Culex http://www.newground s.com/audio/view.php ?id=1639062&sub=5797 2
It is still just a prototype, but here it demonstrates that the conveyor-based pull-back for the firing system allows it to launch K'nex rods more than once. It actually holds up to nine. It's not perfect -- the belt is under high tension and it struggles to let go sometimes.
First fully functioning prototype for my launcher concept showing off the motorized independent tank-treads. It is made entirely of (what I call classic or non-exotic) K'nex pieces and the motors are from Cyber Ultra 2.0. With little change, the chassis could easily be used to convert to the K'nex remote control system (black box).
My K'nex dual Cyclones (inspired by Perfect Dark) work the same way as my K'nexecutioner, so it's more like an upgrade than a stand-alone project. Rotating chain barrels can only do so much, and the barrels are under so much tension that you can even see the lag in the right-side gun as it struggles to flip triggers. Best I can do.
In this video, all four of the motors are used to show that the model is capable of steering and adjusting height to aim wherever it pleases. Really, quite harmless. It shoots blue-lengh K'nex rods.
