Download Lisp to my brain.
If I were a character in the movie The Matrix, I could ask an operator to download a program to my brain so I could fly a helicopter or something.  I would like to learn Lisp and, well, download it to my brain as rapidly as possible so I can start working with it to write a roguelike.  I am looking for good online resources, preferably including a sand-box or similar.  I learned to code my websites by having a template (gifted to me by a friend) and playing with it and I still learn new things when I want/need to do something new on my sites.  I know a little (X)HTML and CSS already and had intro to VisualBasic about 7 years (which I don't particularly remember, of course).<p>Yes, I know I can google this.  But since I know nothing, I can't judge the quality of the sources.  So I am hoping folks here will indulge me.<p>Thanks.<p>PS:  Am I supposed to do an intro?  I just joined today and this is my first post.
