Stone In The Water Rug

rug that looks like someone threw a stone in the water
  [vote for,

This idea is for those who have grown tired of being at home for weeks on end staring at the same furniture; the same walls, the same everything in fact.

Stone In The Water Rug will definitely give you something different to look at every time you throw something unto its upper tufted surface. When you do this, a series of circular ripples begin spreading out from the point of impact, in the same way as they would had the object been thrown into a body of still water.

It can do this because below each of the protruding tufts that make up its surface pattern, there are a series of inter connect micro tubes and valves, all joined individually to sensors and a central controlling programme. A silent running external compressor delivers the supply of compressed air needed to drive the rug's ripple effect action.

On detection of an impact anywhere on its surface, air is sent down the tubes; directed and attenuated by the valves, causing the tufts to flex in order and thereby generating the characteristic pattern effect of rippling water. These circular ripples decay in amplitude as they reach the edge of the rug, in the same way as they would, if a stone had been thrown into a pond.

Two objects will create interference patterns, and using the control panel, it's possible to make all kind of waves moving across the surface of the rug at angles or from the centre to the sides, like the parting of the Red Sea.

Deluxe version can create imitation whirlpool effects, and is strong enough to act as a feet massager.

Like this but different. [wjt, Apr 02 2020]


       Weaving fibre optics into the structure with individual illumination control to each fibre would add a range of extra appearance options.

       True, but was trying to keep the effect as analogue as possible.

       So will you be able to have "skipping rocks" competitions with your brothers, like we used to? Could damage some stuff in your house but that's alright. You can spend all that government money we ain't getting on it. + Bun from me.
blissmiss, Mar 31 2020

       You could skip stones if you commissioned a large enough carpet.
xenzag, Mar 31 2020

       This is excellent. Few ideas evoke a "shut up and take my money!" response for me, but this one has done it.

       I want the heat sensing Gallium version.

       ( ( ( ( ( ( ((((((((((((+)))))))))))) ) ) ) ) ) )   

       We want one that looks like a horizontal version of the gravity drive from Event Horizon.

       Not sure I'd want a stone in my water-rug - tripping hazard.
FlyingToaster, Apr 01 2020


       Could it also be done, more simply, with a very thin fluidized bed where the tuffs act like perpendicular indicators on the surface ripples?
wjt, Apr 02 2020

       Or how about a nylon rug with electrostatic... stuff under it?
wagster, Apr 06 2020

       It could be realised that way, but would you want to give up on the ridiculously complex tubing arrangement required to operate it using the power of "air hydraulics"?
xenzag, Apr 07 2020

       Well, dynamic electrostatics are just as complex, but I see no reason why we can't combine them. That would give us two highly complex interwoven systems which are mutually incompatible.
wagster, Apr 07 2020

       // "air hydraulics" //   

       Tech. "Pneumatics".   

       Systems using compressed gas as an energy transfer medium are pneumatic systems. Specifically, "pneumatic" means "using air", but the term is used for any compressed-gas system.   

       "Hydraulics" refer to systems using water, but the term has been extended to cover any such technology using a relatively incompressible liquid.
8th of 7, Apr 07 2020

       Pneumatics. Of course. Air Hydraulics! Ha
xenzag, Apr 07 2020

       Remember, we're laughing at you, not laughing with you ...
8th of 7, Apr 07 2020

       That's ok. I'm happy for anyone to laugh at me. I just join in.
xenzag, Apr 07 2020

       Is there any way we could also incorporate water- pneumatics?
wagster, Apr 07 2020

       There are such things as "hydro-pneumatic recuperators", using both gas and liquid, used to control recoil in artillery; so mixed-mode hydraulic/pneumatic systems are Baked.
