umm... i'm not even sure if that's even the right 
name for the type of cel i'm talking about but i 
have it stuck in my head at the moment that 
that's what they're called... can anyone help?

and in case 'harmony' cel means nothing and my 
silly brain just made it up, here's a picture of 
the type of cel i'm talking of

thanks a bunch ^_^
