Pharo

I am very new to SmallTalk and Pharo in particular. I like the idea of image based programming and the have followed the works of Alan Kay and Dan Ingalls for some time now (I very highly recommend it). Pharo looks to be quite a capable system and it is calling my attention. I shall do what I can and post my discoveries here. I think the Pharo Zen is one of the most beautiful poems about computing philosopy. I hope that you like it, the emphasis is mine.
