A dome shaped fishbowl with a LED light in the middle of it
that casts a soft light on the room. As the fish swim around
they cast fish shaped shadows on the walls and ceiling.
These might be relaxing to watch as you drift off. Might be
cool for kids rooms. It's like their pets are keeping
them
company having grown to 6 foot versions of themselves.
Turn any room into a sort of virtual under-seascape.

You would need to turn this off during the day to let them sleep.

Top Fin Fishy Fishy Night Aquarium
https://www.google....yvgA8xoCso0QAvD_BwE
The Top Fin Fishy Fishy Night Aquarium is a light-projecting betta tank that provides quite the show. This amazing tank features color-changing LED and projection disks that project colorful shapes on the ceiling. You will love how it looks and what an amazing home it makes for your betta. Only at PetSmart. [jurist, Feb 09 2018]
Somebody did a simpler version of this a year later.

Think I'll ask if they got the idea from here. [doctorremulac3, Jan 06 2021]

Nice one.....[+] See fly version in link. |
|
| |
I like this very much. Aside from the fish, you'd also get ripples, which are very soothing to watch. |
|
| |
In fact, you could probably do away with the fish and just have a ripulator in the bowl. |
|
| |
"Wanna see my six foot octopus?" |
|
| |
I like this idea way more than I think your fish are going to like it.
.><> |
|

Maybe I'll build one of these, see if it works. Simple enough,
all off the shelf stuff. The light wouldn't actually be in the
water, it would pop up into a dome shaped indentation at
the bottom of the tank. |
|
| |
Shadows cast by the bubbles coming up out of the aerator
might be kind of cool too. |
|
| |
Pics or it didn't happen... |
|
| |
Just drew it on a post-it note. Will upload. |
|
| |
Obviously it would come with daytime and night time mode
or "illuminate" or "project shadows" mode to be exact. |
|
| |
I'll put my horrible drawing up. There you go 2. |
|
| |
You could skip the LED if you had a pair of angler fish, casting
horrific shadows of each other. |
|
| |
Wonder of the fish would all turn top to the light? Don't they
do that? |
|
| |
The light might keep them on an opposite schedule. Doing
their job casting moving shadows and night and sleeping
during the day when the light is off. |
|
| |
Nice.
Jelly fish would make for cool occupants as well. |
|
| |
Of course, you could have a real simple version which is
just
a waterproof weighted lamp you drop into the bottom of
any fish tank. Doesn't seem very fun though. |
|
| |
Yea, like the jellyfish a lot. Those are the most relaxing
fish of the ocean. Until you get stung by one like I did
once. |
|
| |
You're supposed to pee on somebody who gets stung by a
jellyfish. Doesn't help, just something to do until the
ambulance arrives. |
|
| |
Well nobody ever asked for lentil on their sting... |
|
| |
Won't this keep the fish awake/confuse them as to their
orientation? |
|
| |
In the days before aquarium heaters were a thing, tropical fishtanks were heated using a lightbulb. |
|
| |
Maybe confused fish will cast more interesting shadows. |
|
| |
I think you'd switch it off during the day to let them sleep. |
|
| |
Throw in a little Jaws movie theme music? Help the little
tiddlers drift off to sleep. |
|
| |
// In the days before aquarium heaters were a thing, tropical fishtanks were heated using a lightbulb. // |
|
| |
We fear that, yet again, you are being perhaps just a trifle disingenuous. |
|
| |
It would be more correct to state, based on the evidence, the testimony of the fire officers, ambulance personnel, and animal welfare workers (given under oath before the Coroner) that "In the days before aquarium heaters were a thing, my Great-Uncle-in-Law Banastre concieved the idea that tropical fishtanks could be heated using a lightbulb." |
|
| |
His enthusiastic - if misguided - attempts to implement the scheme, culminating in the very unfortunate deployment of an Army surplus searchlight in the fourth aquarium hall* at London Zoo, causing the instantaneous demise of the entire collection and blacking out most of South-Eastern England for the best part of three days (but constituting a major cause of celebration in the penguin enclosure) is a matter of public record, an engraved granite memorial tablet, and a number of ongoing lawsuits. |
|
| |
*The observant reader may comment that London Zoo has only three aquarium halls; yes, it does, now. |
|
| |
Nice. Can the bowl glass have a concentrating factor. I think I'd find small weaving schools more peaceful than a big blurry fishy wisp. |
|
| |
//Throw in a little Jaws movie theme music?// |
|
| |
//Can the bowl glass have a concentrating factor.// |
|
| |
I don't think the bowl could. You might be able to put
various lenses around the bowl I suppose. |
|
| |
Make sure you use the right light source. I once
had
an experimental setup in a lab which had a light
shining through a water bath. Water is opaque-ish
to
IR and so absorbs it quite efficiently. After an
hour
of having this light shining through it, the water
would start to boil. This was a 1kW incandescent
light, so LEDs should be OK, probably.
Otherwise, a rather lovely idea. To help start
implementing it, I did a Google search for
"toroidal fish tank" but the only real hit was
another HalfBakery idea (see link). |
|
| |
Apparently it's available at Pet Smart [see link]. |
|
| |
I don't think it's casting a fish shadow. |
|
| |
"This amazing tank features color-changing LED
and projection disks that project colorful shapes
on the ceiling." |
|
| |
I don't know what a "projection disk" is but I
believe it's something that "projects colorful
shapes on the ceiling." |
|
| |
Maybe I'll buy one and use it as the prototype. |
|
| |
Done. They website says they're available at the location
by my house. |
|
| |
// at the location by my house // |
|
| |
Not a house, a home. Specifically, "St. Blunderbuss's Care Home for the Terminally Bewildered". |
|
| |
Do they deliver, or will you have to be escorted there by a couple of nurses to collect it ? |
|
| |
Will the store accept a delivery slip signed in green crayon ? |
|
| |
Shit. What have I gotten myself into? |
|
| |
Oh well, I said I'd do it. |
|
| |
<pulls faces, makes rude gestures> |
|
| |
// Now I HAVE to do this. // |
|
| |
Yes, you do. Everyone's watching. They even have their special Schadenfreude sunglasses on. |
|
| |
// Shit. What have I gotten myself into? // |
|
| |
The Halfbakery. There is no escape. You are doomed. |
|
| |
// Oh well, I said I'd do it. // |
|
| |
That makes you sound like Hitler ... |
|
| |
<BOOOONGGG> "GODWIN'S LAW !" |
|
| |
Bet you weren't expecting THAT ! |
|
| |
It's a mistake to ever be surprised by Godwin's law. |
|
| |
For some insane reason, I missed this gem the first go-round.
So now I must yell my response at the top of my lungs so you
all can hear me down at the bottom of the well.
I LOVE THIS VERY VERY MUCH. |
