What should you do with old Apple hardware? Keep it and maintain it as the company intended, old software and all? Or maybe donate it to a museum, where fellow fans can gaze at its chunky keys and adorably low-res display longingly? Christophe Guinet, also known as 'Monsieur Plant,' has another idea. For his latest project, Plant Your Mac!, the Parisian artist has converted some classic Apple products into tiny gardens. All of the machines, which include the Macintosh Classic, the iMac G3 and G5, now house a selection of lush, exotic plants in unusual, imaginative ways.
