Mental Case is many things - a drop box for your thoughts, RSS for your head, an index of your knowledge - but ultimately, it's just a fun way to remember stuff. And 'stuff' can be anything, from your new mobile phone number to the Presidents of the United States - Mental Case can even help you remember to stick to a diet.
All you do is gather tidbits of information in 'mental notes'. Enter some text, drop in an image, take a screen shot, or even snap a picture with your iSight. Mental Case schedules the note to reappear at future dates. When you have a few minutes to spare, you watch the scheduled notes in a slide show. Mental Case makes learning a pleasure.
