P1020780 Children play with Bit Blobs
From Bleep Labs & Loud Objects. Or perhaps those were Thingamagoops? Whatever they were called, these gadgets didn't seem to do anything other than bleep very loudly as you bent their tubes. Children were swarming this exhibit, probably excited by the noises and the gadgets' cute faces.
Here is a part of the creators' description of this exhibit:
Noise performers extraordinaire
Loud Objects and Dr. Bleep have created the first being of pure noise.
The Bit Blob is controlled by connecting its control pins together, allowing you to bend your way through unlimited sonic madness.
