The spring loaded series includes a wind-up unit which moves the gears and adds action to the model after assembly. Experience the double satisfaction as you see the locomotive spin its wheels, the airship turning its propellers, and the pendulum clock ticking the actual time!

The hand crank series features moving gears that moves by turning the crank, allowing you to control the speed of the gear movement. See the marble climb the stairs and run through the maze, and keep the hand crank steady as you bring the old film to life with the vitascope!

Justice Guard toy rubber band guns make use of the ROKR mechanical gear system to allow loading multiple rubber bands at once. The kit even comes with targets making it even more fun after assembly!

Combine the fun of building puzzle and creating a music box! After assembly simply wind up the spring to play the music. 

Install one of the installed programming disks and watch the magic hand draw artistic sketches automatically as you hand crank the knob and move the gears. Inspired by Leonardo’s mechanical knight from 1495, each kit includes 4 disks that can draw a skull, horse, flower and a lady (same disks include in each kit).

The scale model series includes highly precise laser cut wooden pieces that articulate the details of a truck, locomotive, and a race car. The easy to follow pictorial instructions allows anyone to assemble and be displayed as an artwork once complete.
