"Cosmic mandate: Treat ‘n Retreat"
Still meditating by the Sea ...
I suspect that a visual Sea of Glass is easy to build (for a darkened room and with special lighting): the top would be thick flat glass and the bottom, an inverted dome filled with a still liquid (maybe water) under slight pressure. The visual effect might be a dark, colorful, luminescent lagoon without water movement.

Essentially, glass underneath plywood having a circular opening. An inverted fiberglass dome (probably white in color to reflect colored light) would be attached under the glass and contain the necessary ports for the liquid. But too big in diameter and weight becomes a problem ... if the Sea needs to be parted

. And bubbles in the liquid may be difficult to remove every time the liquid is replaced.
"A child can do it!" Real or faux stars overhead at night would be inspirational!

To create the dome, layer fiberglass (fabric plus hardened liquid) on half of a beach ball, remove ball and trim dome to size, then drill/attach two ports* for liquid. Attach dome to cleaned, circular glass with more fiberglass, then attach Sea dome to plywood. Dome is filled with liquid (using lowest port) when the Sea is in its final position.
* one port in the center of the fiberglass and one near the top edge of the glass.
The top port will be just under the plywood and helps to remove bubbles.

More notes:
1. Fiberglass should overlap edge of glass; this overlap will be under the plywood.
2. Dome may not need to be a half sphere - maybe 77% of the half-sphere.
3. Rigid support under the dome and attached to plywood will be required;
the Sea structure will appear as a table with short legs ...
which is covered with fabric (dark green velour for "landscape"?).
