The Lab

Experiments and playful tools from the JustGains workshop. Less serious than our calculators, just as lovingly built.

ASCII Text Art

Type anything and watch it redraw as block art, braille, 300-odd FIGlet fonts, and Unicode styles that survive a paste into any text box. Every card copies as plain text.

Gym Builder

Design your gym in 3D. Customize equipment, plan your room, explore ready-made gyms, and save or export your design.

Retro Wallpapers

Twenty desktop wallpapers in homage to classic computers, from 8-bit boot screens to glossy gel. Flip through them on a CRT and download up to 7680 x 2160.

More Experiments Coming Soon

The Lab is where we ship the fun stuff that does not quite fit anywhere else. If you are after training utilities, our Tools page has the calculators.
