STEP 2: If you want to change the colour of the fairy dust, change the colour at the start of the script you just copied to the setting you require.
THAT'S IT When your page loads and you move your mouse, magic sparkles (or fairy dust, whichever you prefer) appear, just like Tinkerbell in Peter Pan!
