    "abstract": "We study the dynamics of surface waves on a semi-toroidal ring of water that\nis excited by vertical vibration. We create this specific fluid volume by\npatterning a glass plate with a hydrophobic coating, which confines the fluid\nto a precise geometric region. To excite the system, the supporting plate is\nvibrated up and down, thus accelerating and decelerating the fluid ring along\nits toroidal axis. When the driving acceleration is sufficiently high, the\nsurface develops a standing wave, and at yet larger accelerations, a traveling\nwave emerges. We also explore frequency dependencies and other geometric shapes\nof confinement.",
