| ![Siag][11] Siag is a spreadsheet based on X and Scheme. I originally wrote it out of frustration with the fact that almost no free, good looking applications were available for Linux. It is based on my old program Calc, which I started writing in the late -80's.
The program has existed in several incarnations: text-based curses for SunOS, text-based hardcoded vt52 for Atari TOS, GEM-based for Atari, Turbo C for DOS, Xlib-based for Linux and now Xt-based for Linux (or Unix, really).
