take apart an LCD monitor and put a fish tank in it.
Play pictures of space... "fish on the moon"
We all shagrin about looking into a dead monitor.... why not make it alive?
I used a raspberry pi and pi-cam to take live video of the fish and display the fish feed on top of the fish... and a bit of CV to overlay bubbles on the fish.
Step 1: Materials, Deconstruction and Construction
I used a 19" monitor because it was free. I built two. For one I used the existing backlight. That was the smart idea.
You simply deconstruct the monitor, put the LCD on the front of the tank, and put the backlight on the back of the fish tank.
Step 2: Build an a Tank and Wrap the Display Around It
I built the tank out of acrylic using acrylic glue. It is amazing stuff, fairly toxic, and welds the acrylic together water tight if you do a great job. I did not do a great job so I just put a bead of silicone around the edges to finish the job.
The depth of the fish tank is limited by the video connector that connect the LCD to the power supply/video cable (see picture).
The glue is IPS Weldon-On #4 Solvent Acrylic Plexiglass Glue. You need to buy the applicator. The applicator is just a little plastic bottle with a needle tip for ~$2 that applies the water like glue to the surfaces that butt together. Weight 12 hours and it's solid, welded together.
Step 3: Raspberry Pi.
You can just use your own laptop to power your fish on the moon videos. I used a raspberry pi and pi cam to capture live video.
I mounted the pi on its own stand a few inches above the fish tank.
