     * Tupi is a powerful tool for teaching and learning. After getting the feedback from teachers that use Tupi in their classes, we are aware of the impact of Tupi in the classroom, not only as an "art class tool" but as an excuse to teach a lot of different matters (mathematics, biology, geography, etc).
     * Tupi is a proposal of user experience (UX) looking for providing an intuitive and easy-to-use interface for a global community of users from different age groups. We like to remind us this ambitious goal with our slogan: "from children from 8 to 100 years old".
-    * Tupi is a basic but handy tool pretending to get an spot in the pipeline of small animation studios around the world. As animation exercises are made by children using Tupi, also there are digital artists playing with it to create their professional works. We want to keep enhancing Tupi to make it an important complement for professional animators around the world.

 Now, let's see what happens when you take the set of photographs and you begin to watch them quickly, one by one. For every image you place in front your eyes, your brain starts an interpretation process, but, as you are replacing one image for the next one so fast, your brain is unable to fully interpret the information of the first picture because it has to begin processing the next one. When the flow of pictures is large enough and it passes at high speed, your brain starts to blend the picture's information, creating the illusion of movement. There is when animation magic happens.
-It is estimated that, on average, the human eye is able to process around 24 images per second. If the number of images is equal or greater than 24, then our brain start to interpret movement within the pictures, the sensation of motion.

-Wait a minute! Does it mean that a film is nothing but a huge pile of pictures that pass in front of my eyes at breakneck speed? The short answer is: Yes! However, we must keep in mind that a movie is something a little more complex than that as it's audio-visual content, which means that also it includes a sound component and a lot of additional technical details.

 In the world of animation, every image that compose a film is known as a "frame". You will need to include several frames for every second in your animations. More frames will give you a better illusion of movement, and less frames the opposite effect. The parameter used by the animation industry to measure the density of frames over the time is called Frames Per Second (FPS).
-Currently, there are a wide variety of animation techniques used by the professional studios to create TV and movie contents. Fortunately, we can use the same techniques to create our own productions. Here are some of them:

-This technique is based on taking photographs of real objects. If you have a camera, that's all you need to get started! So, what can I animate using stop motion? Anything you want if you can move it: people, objects, toys, etc.

 The pipeline is very simple, basically it involves taking pictures of the scene you previously prepared following this little trick: take every photograph after you do small and subtle changes on the elements you want to animate. Think of every picture you are taking as a frame of your animation. And that's it! Of course, there is specialized software to support this kind of productions to make easier the whole process.
