Rickhoff augments scenes within a seemingly commonplace environment to depict impractical yet lighthearted situations – including a playground slippery dip facing towards a busy road to a speed bump placed in an unassuming residential street that is actually a daredevil ramp. the visualizations are subtle yet provocative, forcing the audience to look twice to notice the unusual setting infused with tongue-in-cheek wit.
