I havent' read all the posts yet, but you originally asked who was making their own tarot, and I am in the long process of collecting/taking pictures of nature that align with the meanings of the cards. Swords - quills, needles, teeth, horns, etc.
Cups/bowls: rock formations, craters, flowers, etc (Paul has a picture on his camara that is screaming "FOUR OF CUPS" to me when I saw it...)
Spirals instead of pentacles/coins, thinking of the vortecies in the earth being the earth-related symbol - snails, water spouts, clouds, waves crashing, etc.
Wands - sticks/trees.
A rough example would be the picture of the cow, two horns, being the two of swords:
A bull is represented either as the fierce, raging animal that charges ahead, unprovoked, or the stubborn "bull-headed' animal that won't budge, The swords represent action, and two represents balance. The card cautions you not to be too extreme, like the bull. Neither charge ahead without proper analysis, nor stick to your decision without considering options...
Of course, I'd word it a lot better and explain it more in depth.
But the idea is that as people then go aobut life, they can be reminded of the messages and lessons of tarot in everyday life. Remember the cautions, the balance, the good fortune, etc.
Another example was the snakes we just saw on our gathering weekend - There was meaning in that... just need to look at the cards and decide if that was a 'lovers' symbol, a 'three of spirals', or what it meant.
