By Alex Marchetti, Industrial Retro-Tech Journal Published: April 18, 2026

On eBay, original CD-ROM copies of FlowCalc 32 (with the serial sticker intact) now sell for $200–$400. A sealed "Pro Pack" with the spiral-bound Technical Reference Manual recently fetched $1,200. Is FlowCalc 32 better than Ansys Fluent or AFT Fathom? Objectively, no. It can't handle slurries. It has no 3D visualization. It crashes if you give a pipe a negative elevation. flowcalc 32

There is no "dark mode." There are no tooltips. There is only the blinking cursor in the "Node ID" field and the satisfying clack of a keyboard. By Alex Marchetti

I’m Ellen. I’m the primary author behind Artsy Pretty Colors and the DIY site Artsy Pretty Plants. After having to engineer so many DIY and crafts projects for Artsy Pretty Plants, I realized, more than ever, how important it was to have a good foundation for drawing. Every project starts with a piece of paper and a pencil. And even though I have a formal degree in Fine Arts, most of my drawing skills come from practice. Thus Artsy Pretty Colors was born. I’m here to help you or your kids learn to use their creative minds to develop their artistic talents.
