This script checks data, input through a form, for validity. Use it to grab your visitor's attention, if nothing else. This is a bouncing image script, created by using absolute positioning, along with clever math calculations. It charges aimlessly through the page, hitting and refracting off the edges of the browser window. This script provides a web page with an animated effect.
Snow gently trickles down the page, then disappears.
The image used is changeable, so snow isn't the only effect the script can render. This script adds a crosshair, that follows the movement of the cursor, to your document. This script executes a JavaScript based reload of the current page, at a time interval which may be modified to suit your needs. This script creates an effect that fades from black to a background color of your choosing, and can continue on fading into other colors in succession, according to the colors you've coded. Knowledge of number RGB color codes is helpful.
