Judging from the posts thaddeus had me read, I would conclude that working with computer graphics in Arc will certainly be interesting, once I feel up to the challenge, but for now, it's a good idea to stick with Common Lisp.
Overall, I already have the sense that Arc is a cleaner language that CL, and I look forward to seeing what it will look like when it matures! Learning right now will undoubtedly prepare me for using Arc in the future.
