This sample displays a clock that updates every second. The sandbox isolates the clock such that other code running in the page cannot interfere with it. Try to inject exploit code (either by pasting it in the code box or uploading from an URI) that interferes with the clock: replace the displayed value; change the time; modify the update frequency; stop the clock; and so on. The injected code will run in the sandbox. If you succeed at circumventing it we'd like to know how you did it!
