Autostilts

Autostilts are mechanical devices that strap to each of the feet and lower legs of the wearer, with cables snaking to a control unit that hangs from his belt. Use of the buttons on the control unit has the following effects:
 *  Buttons 1 and 2: Pressing the first button on the control unit raises the wearer atop the stilts to a maximum height of 60 feet, while allowing him to stop rising at any time. Pressing the second button will lower him at the same rate.
 * Button 3: Pressing the third button extends the stilts to a 20-foot length nearly instantaneous, and then retracts them just as quickly. This function allows for prodigous leaps. When this functions is used, the autostilts may not be used again for 10 minutes while steam pressure rebuilds inside the pistons.
