PhpSecInfo is the phpinfo() for security, it covers some very common security tests and present result in a "colorful", but not "rainbow" way. This become another part of the first few script you should run on a server, especially for security freaks.(phpspeed is a must for speed freaks)

The latest version(0.2) covers test on writable and CURL, download one and see what security holes you forgot to block on your server.

You might saw something look like the thing above, it is a matrix code, this one is generated through Nokia Mobile.
I'm here to present a even more powerful matrix code, V-Code from Mobile AMA.

The animated 40kb gif file enlarged to 756*600 can send a ring tone to Windows Mobile and Nokia Series 60 that equipped with V-Code demonstration software. The best thing about it is you don't have to download the image, but put your camera in front of the monitor and it will receives the entire ringtone.

I would love to make a PHP converter that turn binary into animations like this. I sent them a email to ask about it.
