Untitled, or Raisins No. 3 (I Hope)

This is a sculpture outside a popular bakery in Happy Valley. I desperately looked for, but failed to find, a plaque indicating artist and/or title; I assume it has a typical title for ambiguous modern art, like 'Untitled', or 'Raisins No. 3'. I fervently hope these are meant to be nuggets of kneaded bread, or raisins, or even boulders. Anything but what they actually look like...
