<div style="text-align: left;">
The Tower of Hanoi (also called the Tower of Brahma or Lucas' Tower,[1] and sometimes pluralized) is amathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallest at the top, thus making a conical shape</div>

The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules:</div>
<ol style="background-color: white; color: #252525; font-family: sans-serif; font-size: 14px; line-height: 22.3999996185303px; list-style-image: none; margin: 0.3em 0px 0px 3.2em; padding: 0px;">
<li style="margin-bottom: 0.1em;">Only one disk can be moved at a time.</li>
<li style="margin-bottom: 0.1em;">Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. a disk can only be moved if it is the uppermost disk on a stack.</li>
<li style="margin-bottom: 0.1em;">No disk may be placed on top of a smaller disk.</li>
</ol>
<div style="background-color: white; color: #252525; font-family: sans-serif; font-size: 14px; line-height: 22.3999996185303px; margin-bottom: 0.5em; margin-top: 0.5em;">
With three disks, the puzzle can be solved in seven moves. The minimum number of moves required to solve a Tower of Hanoi puzzle is 2<sup style="font-size: 11.1999998092651px; line-height: 1;"><i>n</i></sup> - 1, where <i>n</i> is the number of disks.</div>

<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light.</span><br />
<br style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;" />
<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">For this project you'll need:</span><br />

<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.</span><br />

<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the </span><br />

<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">At the MIT Media Lab, the Tangible Media Group believes the future of computing is tactile. Unveiled today, the inFORM is MIT's new scrying pool for imagining the interfaces of tomorrow. Almost like a table of living clay, the inFORM is a surface that three-dimensionally changes shape, allowing users to not only interact with digital content in meatspace, but even hold hands with a person hundreds of miles away. And that's only the beginning.</span><br />
<br style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;" />
<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">Created by Daniel Leithinger and Sean Follmer and overseen by Professor Hiroshi Ishii, the technology behind the inFORM isn't that hard to understand. It's basically a fancy Pinscreen, one of those executive desk toys that allows you to create a rough 3-D model of an object by pressing it into a bed of flattened pins. With inFORM, each of those "pins" is connected to a motor controlled by a nearby laptop, which can not only move the pins to render digital content physically, but can also register real-life objects interacting with its surface thanks to the sensors of a hacked Microsoft Kinect.</span></div>

<span style="background-color: white; color: #333333; font-family: arial, sans-serif; font-size: 13px; line-height: 17px;">Fourteen-year-old programmer and software developer Santiago Gonzalez might just be the next Steve Jobs. He already has 15 iOS apps to his name and dreams of designing for Apple. At age 12, Santiago became a full-time college student and is on track to earn his bachelor's degree in computer science and electrical engineering by age 16. By 17, when most teenagers are excited to just have their driver's license, Santiago will have his masters degree. </span><br />
