Scratch is a new programming language that makes it easy to create your own interactive stories, animations, games, music, and art — and share your creations on the web.
Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create Scratch projects, young people learn important mathematical and computational ideas, while also gaining a deeper understanding of the process of design. Scratch is available free of charge.
In any email you received, as well as on any webpage you are visiting, double click on a numeric amount to display its equivalent right next to it, in one of the 36 currencies you may chose from the toolbar. The rate itself will be displayed on the toolbar as well.

36 major currency exchange rates are read once a day from the Central European Bank, a source that one can trust !
Still works when you are offline using the last rates downloaded, but warning you if they are outdated, which can be convenient with a laptop.
You may also disable the automatic insertion and only use the reading from the toolbar, or hide the toolbar and leave the automatic insertion.
