ABSTRACT:
A set of similar interconnectable flexible toy construction blocks. Each block has three different attachment surfaces. Posts on a top surface connect within rims on a bottom surface for vertical stacking of the blocks. A projection on a front end connects within a complementally shaped receiver on a rear end for horizontal connecting of the blocks. An interior of the projection is complementally shaped to the posts on the top surface, allowing the front end of one block to connect to the top surface of another block. Each block has two directions of flexibility. Horizontal flexibility is provided by dividing the block into separate segments divided by gaps. Each gap is spanned by a thin web. The gaps can change shape when bending forces are applied, causing the block to flex horizontally. Vertical flexibility is provided by hollowing out each segment of the block through one surface, preferably the bottom. The walls of the segments can flex towards each other or away from each other when bending forces are applied, causing the block to flex vertically.
