I made up a Canva feature that doesn't exist. "Canva Video 3.0" — type a prompt, get a finished video. Then I spent weeks building a real 45-second launch video for it. Why fake it? Because spec work lets me show the full process: script, storyboard, design, 2D + 3D motion, sound. Everything I'd do for a real SaaS launch. Honestly, this is my strongest work so far.
