I have a lot of icons of Gods, Goddesses, Animal Guides, etc. who are meaningful to me. Anyhow, I just made a private devotional post to Venus, using her icon, as I have here. Virtual altarspace with built in iconography. Also, the little eye that LJ uses for private posts just makes me think that someone's watching along with me anyway.
FYI: Google Image Search is a great place to find appropriately sized (or close to perfect sized) icons for LJ, especially of Gods.
Provided I could locate a full pantheon as needed, I think I will make this a part of my daily cycle of devotions. I write in LJ all the time anyway.
