Time Capsule E-mail
Here is a really interesting one from Forbes. You can send yourself a time capsule e-mail about what is going on in your life right now etc etc etc and it will send it to you 1,3,5 or 10 years from now. This is pretty cool and something that could just be sort of fun to do. The only thing is what if you change your e-mail address? it would be like if you forgot where you buried your Time Capsule I guess. Well check it out and let your future self remember your past. Check it out!
