Abstract: A letter tile word game has letter tiles that are formed in an octagon shape, where words can be played not only vertically or horizontally, but also diagonally. Further, the letter tiles have features that permit tile interlocking when building words from the letter tiles, the interlocking feature being available in each of the horizontal word building, the vertical word building and the diagonal word building. The game does not require a separate board for play. With the interlocking nature of the letter tiles, a user can easily rotate the tiles if they want to view the game right-side-up during their turn. Further, should the game be jolted, the letter tiles, being interlocked together, do not inadvertently separate.

Abstract: A wall repair system includes a balloon that can be inflated within a wall space behind a hole in the wall. The balloon itself, or a backer board attached to the balloon, can provide a surface for placement or build-up of wall repair compound so that the repaired wall has substantially the same thickness of the original wall and so that no tape or patch needs to be placed on top of the wall along any location surrounding the hole. The backer board can have one or more threaded holes therethrough where a threaded rod can be inserted into the threaded holes to contact a wall surface opposite the hole, causing the backer board to stay in place against the back side of the wall having the hole therein, thus blocking all or a part of the hole.

Abstract: A toy racing car can be propelled via various manners, including, for example, a pull-back recoil mechanism, a remote-control driven battery powered mechanism, or the like. The toy car can include one or more activators that, when activated by an impact against another object, eject the “driver” in the car or a portion thereof, such as a head that extends from the toy car.
