Abstract: According to an embodiment of the disclosure, a computer implemented method and system comprises: presenting, via a display, a plurality of code tile fragments; receiving, via a user interface, a first input that maneuvers a first one of the tile fragments onto a first layer of code tiles, the first one of the tile fragments representing a first portion of an expression or statement; receiving, via the user interface, a second input that maneuvers a second one of the tile fragments onto a second layer of code tiles, the second one of the tile fragments representing a second portion of the expression or statement, wherein the second layer of code tiles is superimposed on the first layer of code tiles; generating, via a processor, the expression or statement based at least in part on the first and second tile fragments; and presenting, via the display, the expression or statement as stacked first and second layers of code tiles.
