Showing some style at work can be cool, as demonstrated by reader Keith who submitted the following . . .

Filed within the category of "what-to-do-with-this-old-tube," and when you've already made a wallet, a box of tire boots, swimming pool patches, MagLite holders, and sweet pro-wrestler-style bicep bands: if you work in a call center or any office that supplies headsets for your desk phones or VoIP system, I present another use for your discarded inner tubes: the headset hook.
The product of conference-call boredom yielded this really simple, yet effective and stylish, use for the Presta valve section of an inner-tube:
Use scissors (or ceramic diving knife -ha!-) to cut out the valve-stem section of the inner-tube, leaving about 2cm on either side of the valve itself. I then used two "T-pins" (basically long push-pins with a t-shaped metal head) to hang it from our standard-issue cubicle foam-board section. Should work similarly on any cork-board, or, into drywall with a good staple-gun or picture-frame nails.
I pushed the t-pins through the tube on either side of the valve. The pins should protrude through the back of the inner tube and into the cubicle foam-board. I positioned the pins along the upper edge of the tube itself, pointing downward at an angle into the foam-board, to allow the tube section below the pins to provide cantilevered support for whatever ends up hanging from the protruding valve-stem. Placing the pins too low would result in a sagging, sad, and floppy "hook."
The resulting "hook" likely won't hold anything heavier than a few ounces, but, for my headset it's perfect. Though I don't have photos of the sturdier version, you can produce a hook which carries far more weight by removing the valve from the tube entirely and affixing it through a hole drilled through a thin strip of metal stock, using those leftover Presta-valve nuts. This works best with extra-long valve (60mm) tubes.
Anything is possible - but, be sure to use the also oft-discarded Presta-valve cap, to avoid snagging any clothing you might hang from them. If you envision several extra-long Presta-valve "hooks" affixed and spaced evenly through a 4 foot wide section of 1/2" thick stained walnut, you could really dress up an otherwise boring bike-shop employee coat-rack, or something for the back of the closet door in the "man-cave." When I get around to that, I'll re-post with results!
For now, for my headset, this light-duty, simple re-purpose of the Presta-valve section of my latest trashed inner-tube keeps my headset out of the way, and adds a subtle "cyclist-works-here" touch to an otherwise stark corporate cube-space. A functional conversation piece!
