Somebody from Chennai actually tipped me about this and found the advertisement while skimming through the serial "kolangal" :)
I recorded the ad portion and made a quick flash movie out of it for my own reference. Looks like they have used some of the designs from the rangoli pages as spinning images in the background. In some instances, they have changed the colors of the original the designs.
While I'm happy about this, it would have been even more gratifying if they had asked us before using the images. :(
Thanks for letting us know about this ad.
While building this section, I dug this up from the archives of our older system! I kind of hesitated before adding this entry under the media section, but decided to add it anyway, to draw attention to the copy-paste culture which undermines the work of the authors.
