Anyone know what this old Linux game was called?

Used to have this game on Linux at least a decade ago- fairly simple art design, just spherical blobs, as I recall. You controlled one ball, and you sling-shotted it around- smaller balls you'd absorb, I believe larger balls would destroy you, and you'd ping pong off balls of similar size.
I may be misremembering some details, so, with my appreciation, just feel free to gimmie the names of any Linux ball-bouncing games that sound somewhat similar. :P
