I will make an Image viewer in JavaScript( a web application) which will be similar to existing python Image Viewer in Sugar and will have additional features. The application will be made for students. It will induce creativity and learning through its playful user interface and fun tutorials attached with it. The detailed structure of the application is explained further.

4) Control of RGB colours to induce learning and creativity. Three sliders for R, G, B, with which children can increase or decrease respective values of the pixels of the image. if they increase all of them by same quantity brightness will increase so they can understand how brightness changes!
4) RGB controllers. Three sliders for R, G, B, with which students can increase or decrease respective values of the pixels of the image.
5) For convolution filters, we can have an input matrix(3*3) in which weights can be adjusted by the students.

* The application will have a Plugin mechanism for adding further effects and features.
* The application will have a “'''fun facts”''' or “ '''tutorial'''” section. In this section children will be introduced to the world of pixels. How pixels make an image and how they can be manipulated using the application. Each filter will be explained through description/ images/ animations. This will encourage them to think out of the box and if they think their effects created through RGB data manipulation, are good enough they can create their plugin.Reference links for further study will be given.

How pixels make an image and how they can be manipulated using the ImageViewer application. Each filter will be explained through description/ images/ animations. This will encourage them to think out of the box and if their effects created through RGB data manipulation are good enough they can create their own plugin! The RGB controllers can explain how pixels values can be changed in an image. Incresing all RGB values with the same amount increases the brightness, taking average of RGB values can give grayscale effect, for advance filters like blur,sharpness, edge detection which use convolution filters, an input matrix (3*3) will be made so that students can enter different weights and see the consequent result. All these will be accompanied by live examples explained thoroughly in the tutorial section. Reference links for further advance study will also be given. ( A demo of this can be seen in the prototype mentioned below)
