Scamper is Squeak's webbrowser. It is capable of browsing simple html including gif-pictures, and is used to display Squeak Help.
You can also use it to browse the internet, but you will find that it doesn't display most websites well, for these tend to contain html-stuff Scamper can't display, such as tables. But it is a useful to display simple html on your disk including gif-pictures, and enables it to have your own html-files inside Squeak, provided the html in the files is not very complicated.
And Scamper has the great advantage that any code in it that can be run by Squeak can run in Squeak. Here is a simple example with a link: Highlight the following paragraph and do Cmd-p
Time dateAndTimeNow. "Nice display of present date etc. according to the system clock. Do Cmd-b on Time to have a look at the code in a Browser."
Likewise you can calculate easily and fast in Squeak in Scamper
50 take: 25. "The number of distinct ways to select 25 from 50 items. Do Cmd-m on take: to look at this method. You can edit the numbers inside Scamper to learn about how very many choices there are from just a few things."
For more see Workspaces, in which there are more possibilities than inside Scamper.
