> I got a big porcelain board for 5 bucks on eBay because one corner was dented. Best purchase of my life.

In case you or others aren't aware:

Bathroom tile backer board is commonly sold at big-box home improvement centers for a very low price per 4x8 foot sheet of material. It's the exact same stuff as commonly sold whiteboards, just without the aluminum edging and large price.

I've worked at a couple of employers who had open-plan style work areas, with the walls lined with such boards. Everyone had a set of white-board markers and a rag or eraser, and maybe some windex.

It's a cheap and practical solution for brainstorming and other uses software engineers often find themselves involved in.
