From a passing comment to a prototype in 3 days.

It started at a cross-country carnival. I was watching my daughter run when I bumped into one of her friend's mums. She mentioned she'd bought a building set for her nephew and was disappointed it arrived in nothing but plain brown packaging. "I really wish somebody would just build a box that looks like a brick," she said. "If you make it, you owe me 10%."

She was laughing. I was already thinking.

An hour later my brain hadn't stopped processing. Within two hours we had the name. Within four hours we had a website. By hour five we had engineering schematics and a plan for how the box would actually work. At seven hours I was standing in Officeworks buying materials for the first prototype.

Three days later, BRIXBOX was sitting on my kitchen table.

Some ideas take years. This one took a conversation, a carnival, and a sheet of cardboard.
