For fun and having a laugh with (sometimes) a new perspective on things.
A blog where you can post these parallels between major news subjects and entirely different prosaic ones. For instance a headline: “Here is why a Trump rally is like a kids birthday party.” Then write a post about the similarities.
Email is an open system. Anyone can send an email to someone else if they know their address.
An email system following these rules:
1. Only messages from an email address on your whitelist get to you.
2. Any other email is bounced back automatically.
3. You can put email addresses of others on your white list by hand.
4. You can also do so by sending them an email from your address.
5. You can give the other person a one-time token to send you (in the subject for instance) that would automatically put them on your white list permanently, or only allow this one email to pass through to you, and then you can decide to give them permanent or temporary (up to X number of emails, X amount of time, combination of these, etc.)
Currently, the same amount of water is used each time you flush.
Have a smart toilet that can sense and measure the amount of body waste you deposit in it, and adjust the flushing accordingly.
As a fun game, teaching and marketing device.
Start with the first page. Explain how the game works and give the first lesson. At the end of the lesson give a clue as to what to search for on the site, based on what you have just taught.
They might need to use the sites search (if the found out what to search for), or complete an address (URL) to find the next step. Give small bonuses or prizes on each phase to encourage them.
Anyone (or just the first one) who completes the whole hunt gets a big prize.
The clue to the next step is always based on the last page, and the lessons learned so far.
You go to a store (a book store for instance), and you are interested in a particular subject. You find the shelf you’re looking for, but there are so many options, that unless you already have some knowledge, it’s hard to decide what books to buy and in what order to read them.
Make an appointment with a specialist and specify what you are interested in (for instance books about the history of science, or productivity, etc.) You’ll meet at an agreed upon time at a big store, and he will do a whole tour of the subject with you, and give you an independent advice on what to buy.
