It felt, and still feels, to me very much like the failed UI redesigns we've seen from Google as of late.
Even after giving it some time, I still don't think I'm better off with DDG's redesigned site than I was with its old design back at the beginning of May.
It may not be a complete UI disaster like the Google Maps redesign, for example, but it's still unfortunately a step in that direction. I sincerely hope this isn't a continuing trend with DDG.
