The Quirky Website of the Week is a regular feature on this site. Feel free to recommend other quirky websites in the Comments section.
If you are looking for a website that doubles as a virtual magic trick, be sure to visit PeterAnswers.com. Using the software, you can fool your friends and family by knowing the secret to the trick.
In the first dialogue box, type a period, then the answer to the question, then a period. Finish typing the phrase "Peter, please answer the following question:" including the colon.
Then type the question that your audience tells you to type, including the question mark.
Peter "magically" knows the answer to any question with the secret period-ANSWER-period code, which appears on the screen as if you are starting to type "Peter, please answer the following question:" When your audience members try to type, they will not know the period-ANSWER-period code, so they will not get Peter to perform.
Pun intended, I am afraid, but enjoy the site anyhow.
