Marble and Laurel appeared (along with Elsie) in my first comic about Second Life, which was also a 24 hour comic. In the first storie Elsie barely appears as she swaps places with Laura_S, (a version of myself) and promptly gets transported to "1st Life". I plan to use the 3rd Rock version of Marble again, someday.
