Generating free QR code with custom colour, background, design, etc.

I just discovered this website that enables us to generate QR code with custom colour, background, design, etc. for free.

Here is the QR code of my blog generated by that website. Pretty cool isn't it?

Currently it only support 5 types of QR code generation, which are:

• Text
• URL
• Phone number
• VCard / meCard contact detail
• WiFi Access

And supported customization includes:

• Round the edge of the pixels
• Change background colour
• Put an image as background
• Change foreground colour
• Change colour of certain pixels
• Put an image as foreground
• Paste an image in front of the QR code

This is the website I'm talking about: http://www.qrhacker.com/
