Claims: What is claimed is:

1. A toy kit for exercising the creative ability of children comprising a plurality of individual units, each of said units having upper and lower faces and carrying cooperative integral means laterally of said faces for directly interlockingly uniting the same together with said upper faces in side by side relation in a desired pattern so as to create a flat generally horizontally disposed base, a plurality of pinion wheels, at least two of said pinion wheels and two of said upper faces of said individual units having mutually cooperable means for rotatably mounting a maximum of one said pinion wheel per individual unit, and said at least two pinion wheels and said two individual units being so constructed, arranged and dimensioned that said at least two pinion wheels are in meashed relationship when said at least two individual units are united by said integral uniting means.

2. The toy kit as defined in claim 1 wherein at least said upper face is planar.

3. The toy kit as defined in claim 1 wherein said lower face is planar.

4. The toy kit as defined in claim 1 wherein said upper and lower faces are planar.

5. The toy kit as defined in claim 16 wherein said means for rotatably mounting said pinion wheels relative to said individual units, are cooperative apertures and shafts.

6. The toy kit as defined in claim 5 wherein at least some of said individual units are devoid of said mounting means whereby a pinion wheel could not be mounted for relative rotation thereupon.

7. The toy kit as defined in claim 1, wherein said cooperative integral means includes grooves and projecting ribs, and the grooves and ribs of one unit interlocking with the ribs and grooves of an immediately adjacent unit to form said base.

8. The toy kit as defined in claim 1, wherein said cooperative integral means includes grooves and projecting ribs, the grooves and ribs of one unit interlocking with the ribs and grooves of an immediately adjacent unit to form said base, said grooves of each individual unit being arranged in pairs, and said ribs of each individual unit being arranged in pairs.

9. The toy kit as defined in claim 1, wherein said cooperative integral means includes grooves and projecting ribs, the grooves and ribs of one unit interlocking with the ribs and grooves of an immediately adjacent unit to form said base, said grooves of each individual unit are in parallel relationship to each other, and said ribs of each individual unit are in parallel relationship to each other.
