Could be just a matter of taste, but that's code that can be read and is efficient, and is probably decently designable according to (as I learned as early engineering student) nassi-schneider diagram and progressive refinement, so also formalizable. How often does that happen in modern software province? ---- [ALM] Added resizing stuff (now you can resize it "freely" until 6000x4000 pixels, guess that's enough.

When I run it, the clock appears, and then it shrinks to the upper middle and quickly vanishes. If I redisplay the clock (hide it behind another window or iconize it and then uncover or display it), the clock reappears, and then shrinks off into the distance again. (This is running on Microsoft Windows XP with ActiveTcl 8.4.1.0.) Doing a little more investigation, I found that the value for '''radius''' was steadily decreasing until it reached the value -1. [ALM] Uh, sorry. That didn't happen for me, and sure, I know why, and changed it now (just that people don't think you're crazy ;). I hope it's ok now. ''[escargo] 17 Oct 2003'' - All better now.
