Estrelinhas caindo do cursor do mouse com efeito arco-íris

Oiii, na postagem anterior, eu ensinei voces como colocar estrelinhas caindo do cursor do mouse , mais hoje irei mostra quase a mesma coisa, mas com as estrelinhas caindo com qualquer cor, igual esta no meu blog , é super facil ;D



1° copie o código enorme :





&lt;script type='text/javascript'&gt;

// &lt;![CDATA[

document.body.appendChild(tiny[i]=rats);

tinyv[i]=0;

rats.style.backgroundColor="transparent";

2° Vá em design -&gt; Adicionar Gadget -&gt; HTML/JavaScript -&gt; Cole o código enorme (mais não coloque título )



Beem fácil ! ;D
