paula.paul (Birgit Paula Reiger & Bernd Stelzer) / Lubie (Genevieve Beaulieu & Claudine Thibault)

At first glance, you might not think this is the most realistic flower ring you've ever seen.

But first glances can be deceiving. This "ring machine," by Austrian designers Birgit Paula Reiger and Bernd Stelzer of paula.paul, includes a hidden button that controls the petals and stem, allowing them to droop or blossom as a real flower would.

Bonus link: it's tough to beat the realism of actual flowers. Genevieve Beaulieu and Claudine Thibault of Quebec's Lubie use real flowers, shells, leaves and quartz in their spring, summer, fall and winter collections, respectively.
