Design an outdoor TV Enclosure for 32" flat screen TV to be used outdoor such as backyard, pool, or cafeteria. - Inside the enclosure will hold flat screen TV with dimension of 30" x 18" x 2" (W x H x D). Dept can be extended if needed. - TV must be safely secure inside the enclosure when not attach to the VESA Wall mount - Must be able to mount with VESA Wall mount standard of 200mm x 200mm - Water resistant but does not need to be completely waterproofed - Have a cooling system, either ventilation for airflow (Fans) or cool down liquid (Freon) - A sound bar will be located in the bottom of the enclosure - Would be nice if the enclosure has feet that can be pushed in or pulled out when place on the ground to keep it balance.

The spiral of learning (Kolb & Kolb) is a simple helix visualising the learner's progress. I need to visualise a more complex spiral. Turns on this helix are circular. Each turn represents an interaction between teacher and learner. This helix contains 1 grand turn. A grand turn contains at least 3 smaller turns. This creates a turn complex. Each turn achieves a small or large rise on the z axis depending on the diameter of the turns on the x and y axes. In elevation view the turn complex should have a stepped appearance due to the presence of the smaller turns, with the lowest steps at left and the highest at right. The idea to be communicated is that the larger turns contain at least 3-5 smaller turns. Each turn achieves a small increase in z-height as the learner exits the turn, like freeway traffic using a cloverleaf junction. Multiple interactive turns aggregate to a large gain in z-height. In the attached illustration, the largest loop should be understood as not a part of the visualisation. I would like to see two variations of the design: (1) smaller turns ranged on outside of grand turn diameter (2) smaller turns ranged on inside of grand turn diameter.
