Vishnu and an L. Ron Hubbard alien, painted against the pepto-bismal background of a three-story high, open-air mural, has never been able to contain its amusement at the city's impotence to make Block 37 anything more than a square-block dirtpile since it rushed to demolish every structure on the block - save the ComEd substation on which the Plug Bug is painted - in 1989.
Finally, however, the last laugh may be dawning on the Plug Bug, itself. As you can see from the photo below, construction is actually progressing on Block 37, including both a new tower that will be home to CBS/2's street-level studio and a block-long retail complex along State Street across from the Marshall Field's/Macy's flagship store.
Like Aida and Radames, the Plug Bug has been condemned for its insolence, and is now being entombed within the newer structures going up around it. Thousands of years from now, when future archeologists pull down the last steel beams of the buildings currently rising, the Plug Bug will again be revealed, and future peoples will be amazed and perplexed as they create their own stories of what it must have meant to we lost-in-time primitives of today.
