Though, my idea was to use clear flexible vinyl sheeting. It is used in the refrigeration industry to form strip curtains. I just looked online and saw at Tap Plastics, 1/8" thick, by 12 inches wide, x 200ft long role for $3.50/foot. That was the widest they had. Interstate Plastics has some rolls 48" wide, x 60ft long and 0.120" thick for $630. <br></div><div id="yui_3_16_0_1_1504273591925_63055"><br></div><div id="yui_3_16_0_1_1504273591925_63056" dir="ltr">Then add edge emitting LED strips along the edge. But, I am not certain the light will not just concentrate on the edge alone, unless you do something to disrupt the surface. <br></div><div dir="ltr" id="yui_3_16_0_1_1504273591925_63284"><br></div><div dir="ltr" id="yui_3_16_0_1_1504273591925_63287">Perhaps a sander or wire brush on a rotary tool would do it. I wonder if gelatin would do the same job, and leave the plastic unharmed. I imagine using fairly thick gelatin, so that as you drag through it, the brush strokes remain.<br></div><div id="yui_3_16_0_1_1504273591925_62780"><span><br></span></div><div id="yui_3_16_0_1_1504273591925_63236"><span>-Joe<br></span></div></div></body></html>
