‘Yesterday's Today’ displays last week's weather prediction for today through a real-time simulation that reveals the gap between projection and reality. Installed in Chelsea and Westminster Hospital examination rooms, the work renders digital landscapes using forecast data from exactly one week ago—if last week predicted sun while rain falls outside, the digital environment remains stubbornly sunny. This temporal disconnect makes visible when data loses predictive value, when information transforms from useful to obsolete.
The simulation's gentle errors—wrong cloud formations, misplaced sunshine—offer meditation on uncertainty inherent in all predictive systems, whether meteorological or medical. By making forecast failures beautiful rather than problematic, the work suggests living with uncertainty becomes more bearable when we remember even sophisticated predictions remain educated guesses about tomorrow.
