I just bought a whiteboard. Oh, how I love whiteboards! Those great big open expanses of scribble space are truly inspiring; they free the mind to wander.

My other favorite scribble spaces:

• my Moleskine notebook
• a great big office desk (cleaned off regularly to remove unwanted distractions)
• a large LCD monitor
• Notepad++
• 37 Signal’s Backpack, Basecamp, and Writeboard
• Microsoft Excel (go to Options > View > Gridlines, and turn off the lines)

Bliss.
