If you need to bring up the Windows Task Manager...well, you're going to have a bad time. Anatoly Vyatkin's keyboard sculpture in Yekaterinburg, Russia consists of 86 blocks of concrete weighing up to a thousand pounds each:
The landmark, which was designed to mimic an IBM PC keyboard, incorporates a piece of technology into the natural landscape, promoting the idea of integration and inviting passersby to interact with it. Pedestrians in the area often find themselves playfully hopping onto the "keys" of the installation, despite knowing it serves no immediate function. The installation provides a whimsical bit of art for the public that is still very relevant. It will be interesting to see how future generations perceive it once keyboards have become obsolete.
No doubt they will say, "A keyboard. How quaint!"
