Drawing inspiration from Japanese Soma-Toh or a revolving lantern, which displays a colored silhouette, designer Mac Funamizu has devised a transparent USB memory stick that illuminates to indicate the data saved, or space available for that matter, within. Synced with the icon on your desktop, the flashy pen drive distinguishes data with different colors, such as pink for images, blue for documents and green for movies. The memory stick, when translucent, indicates the availability of storage space within, while on the other hand, the glass flashing with light signifies unavailability of data space, so you could scan it to fill or remove data without going through its memory status on your system.
