CSS: An Expanding Circle Transition

As the image scrolls down, a CSS filter is applied. In this case, it’s a black-and-white filter to wash out the colour. Other options include a sepia filter, a blur filter, a zoom filter.

Title Case Regular Expression

You feed in a string to a regular expression and it comes out in Title Case. As Perl, PHP and ASP use regular expressions, this expression is useful with a little tinkering: $x =~ s/(\w+)/\u\L$1/g; $x =~ s/(\sand|of\s)/\L$1/ig if ($x =~ /\sand|of\s/i); Enjoy!
