Well, now any kid can make a card with all that stuff, without needing to know how to write a single line of code!
All you need to do is open the texture Template (included) in your own graphics program, draw your card, write whatever you want to say, save it as a .tga file, and upload to SL. Putting it on the card is a simple, because there's only one texture sheet.
Use any sound clip you want, any texture you like for the particles, or don't use either one, if you don't want to.
When anyone touches the card, it'll open, play your sound, and poof your particles into the air. If they touch it again, it'll close (without any sound or particles, of course.)
Since you're making the card, it'll be exactly what you want it to be, and really precious to the person you're giving it to.
Mod/No Copy/Transfer (so you can give it away, of course.) Only L$75, so you can afford to give them to people. On sale now at Kick the Can, Livingtree (149, 130, 24). Look for the vendor with the Gift Boxes in it.
That's Kick the Can if you can click on links in this forum.
