USB key of the Belle Époque
Your data can go steampunk with Rob Smith's Mechanical Memory Key collection. Key No. 4, shown here, is made of Paduak wood and holds 16GB.
The eye is instantly drawn to the USB stick's collection of gears, levers and brackets, which make it look more mechanical than electronic. Made of parts from six different period pocket watches, the elaborate works don't actually move, although the embedded rubies can give the appearance of motion when they catch the light.
It has a matching cap and an elegant brass-trimmed semicircular cutout for attaching to a keychain or necklace. Mechanical Memory Key No. 4 is no longer available, but Smith offers similar handcarved wood and clockwork memory keys (sans rubies) at his Etsy shop for $140.
