Off By One Error | Funny Computer Science Student Humour
A cute array of numbered boxes where the little character has climbed into the wrong one and is peering out sheepishly, one empty box glowing red beside it. The banner reads "OFF BY ONE".
The first bug every CS student meets, and the one that never fully goes away.
Hand-drawn illustrated design with bold outlines and flat colour, printed as a die-cut sticker or on apparel.
