I have been playing around recently and making video greeting cards to send to people using Oovoo I got sick of paying a fee for online greeting cards when they were still impersonal and annoying like a conventional greeting card. For my nieceâ??s 4th b-day I put on a silly hat and sang her happy b-day and made a bunch of animal noises, she loved it â?? it took me five minutes, and it was free (well, I suppose you have to have a webcam).
