STEP 2: If you want to change the amount of smoke that is produced, or how 'big' the smoke that rises is, change the values at the start of the script you just copied to the settings you require.
THAT'S IT When your page loads, every time you click your mouse, your cursor will release a thick deep smoke as if it has been miraculously turned into a Cuban cigar or French cigarette. This script might be of use to those who enjoy tobacco or perhaps if you just want to make it look as if your page is being set on fire.
