1. Using the UserInfo class, you can get access to data of the user (if he's logged in), including it's picture 2. thanks. 3. Look at Spilli's account, he's got a scenario Matrix Effect.

@tylers It was inspired by that, but the code is my own :). And I haven't got the 'I forgot my password' feature. While I haven't added it, you'll have to ask me for your password, since only I have access to it :). Others of course need your greenfoot account password to access your account on this app, so I think it is quite safe.
