Roaming through the PSE building I come across a solid steel door. Above the door is a sign saying “Astrodome R”. I had no idea this place delved into astronomy.
Below this sign is a painting of sorts:
Obviously abstract, but I kind of like it. Below the painting is a little rhyme:
Roses are red
Violets are blue
Least pushes is best
Binary is good too
At the side of the door is a four digit display currently showing 0000. Below the display are two push-buttons. The left button has imprinted the text "x10" while the right button has the text "+7". Above the display is the text "Immediate calculation. Only 4 LSD shown".
LSD? Is this perhaps a storeroom for drugs?
Can you help me figure out how the 2 buttons should be pushed to open the door? And what might be behind the door?
Hmm. Four rainbow colored sections in the painting and four digits in the display. Could there be a connection?
I take a chance and try the door handle. Locked, as expected. In frustration I randomly press the two buttons for a while. The display shows 1249. The door remains locked.
