Oh definitely :P. But, note that it's been tried before by white Rastafarians. They mention California, so that would be Eddy Lepp's case... the Feds really didn't like Eddy. Eddy cited scripture (Rasta) which instructed him to grow it, but to also offer at least 1/3 of his land for others to grow on. So.. 32,000 plants wasn't something the Feds could look past.
I have plenty of things with Her symbols on them, some of them even lived on my altar for a while when I had one (didn't pray, meditated with it in my peripheral vision, when I started neopagan/zen mashup practice).
All my altars TO Eris are transitory pieces of art, like sandcastles or stacks of rocks (see also the Myth of Starbuck's Pebbles), or Cram's PosterGASM posters.
