slightly off topic : maybe this is the right place to ask: i’ve seen a post a few years ago about a revolutionnary language to program the web, very graphical programming oriented, extremely ambitious, but for the life of me i can’t remember its name. Does anyone here think he knows what i’m talking about and could help me ?
