Let's make this birthday one to remember.

64 years old (Born on April 28, 1961)

Happy Birthday, Grenville! May your day be as bold and intriguing as HAL—though hopefully less abstract. Your sculptures have always challenged our perceptions; who knew two steel objects could spark such artistic debates? And let's not forget that human-sized gold table—you've truly set the standard for furniture envy everywhere.

Your Turner Prize win in 1992 remains legendary, proving once again you can turn metal into magic (and critics' heads). Here's to another year of sculpting brilliance—and perhaps creating something even more puzzlingly wonderful than before. Keep shaping art history with humor and style—we're all watching closely!
