Chocolate samplers, red roses, conversation hearts—you can do better than clichés this February 14. If your valentine is a design connoisseur with a particularly discerning eye, you need look no further than this adorable wallpaper by Brooklyn-based designer Aimée Wilder. Called "Love Molecules," the repeating motif is inspired by the molecular structures of 12 hormones and neurochemicals, which are "essential for life, love, and happiness," according to Wilder. Not ready for such a longterm commitment? Try the designer's Amour prints, silk-screened posters of the Love Molecules pattern presented in a heart.
