Here’s something I did for fun in May as a proof of concept. It uses JavaScript and the canvas tag to render a Super Mario Brothers style tile-map with background. Try it in Firefox 3.5+, Safari 4+, or Chrome/Chromium.

Secret (Tiny) Message Encoder

Having seen the smallest readable bitmap typeface (3×3 pixels per character), I decided to hack up a small JavaScript/canvas web app for fun so people could try it without having to install a TTF file.

Then, the “secret message” idea struck, so I made the “secret” message encoder. (Warning: Only tested with Firefox 3. It also requires the canvas tag and doesn’t yet work in Safari.)

You type in a message and it will give you a link you can send to someone to view their super-encrypted message.

Always great to find an excuse to play around with
