Chair made of drinking straws

Scott Jarvie made this Clutch Chair using more than 10,000 drinking straws. This one is apparently a non-functional art piece, however it seems like one should be able to make a usable chair with the same materials.

Anyone know how to form a curved surface using only straight segments of straw? My best guess is that you could use half-length straws as a wedge to form the curves. [via neatorama]
