Inspired by the computer of my childhood, the Amiga. I thought why are there no editors that have really nice graphics. If there were maybe more young people would take up programming as a hobby.
This example uses multicolor fonts but I am sure one can do a lot more to make the text editor inspiring.
What if it is possible to take advantage of Internet peer grading to enhance schools in rural areas with small resources. With the use of mobile technology like a smartphone or tablet equipped with a camera and a limited Internet connection. The student could photograph his paper and pen solutions of the extra exercises and upload them to a private site for grading. The idea is that the student could use this option in before taking a test.
Example using a simple smartphone and a document scanner application.
