Wiremod is so much fun using when making things.
My favorite thing is the glider.
All you do is spawn a PHX 1x2 plate.
Use smartsnap to make wire-thrusters with thrust-multiplier set to 1 on the corners.
Put wire-speedometers right next to them, make sure they separate x,y,z.
Then wire up the thruster_a to speedometer_Output: Z.
Fling it around and have fun.
