Vivayor

Vivayor (요르가 in Korean) is a character owned by Jamtainment, which appears to be from 2002. His official website is no longer around, but is accessible via the Wayback Machine (vivayor.com). A site called vivayor.co.kr had a discussion board where you could talk about Vivayor.

The website had Flash animations of Vivayor, a white and blue dog with star-shaped eyes, who loves to exercise, and a white and pink cow named Kow (코우가), who was sometimes depicted as a rival. I feel bad for the cow, since it's unhappy in most of these Flash videos. The website also had Flash eCards depicting the two characters, and a "Cartoon" section, but I don't know what was there, since the eCards and sports animations were in other categories. It also has a "Letter" section, but it doesn't look like anything was initially added there?

The "Cartoon" section seems to have had two episodes.

Downloadable Content

Some content put up for download on the site, such as three wallpapers, a calendar, a Winamp skin, and animated gifs, weren't archived. Only three Flash banners were successfully archived.

Animations

Five sports-related animations, a Flash file for an opening theme (that isn't used for the videos), and Four Flash eCards were archived.

Syncro Dance

I so don't have info on this. It's a Flash dance game (ofc) that doesn't appear to have been archived. It may have been published to the site on the 19th of November, 2002 (or at least around then, since this was the announcement date).

Flash Videos

Not meant to be in order of release. I suggest muting each Flash file after playing one after the other, since the music will probably keep playing after you pause them. The first video has frames that flash fast.

eCards

The title above each one is just the category name they were given on the official site, not the name given to each video.

Banners (SWF Downloads)

Credit to those who archived content on Vivayor's website and jqbar.com for having some of the animations archived, as well.
