Hoje, dia 23 de julho, é o aniversário do Textual, e ele muda seu ícone para o dia. Do código-fonte :
The first public commit of Textual occured on July, 23, 2010. This is the day that we consider the birthday of the application.
Trecho do código-fonte mostrando a condição do ícone diferente:
/* THIS IS A SECRET!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Birthday icon designed by Alex Sørlie Glomsaas. */
NSCalendar *sysCalendar = [NSCalendar currentCalendar];
NSDateComponents *breakdownInfo = [sysCalendar components:(NSDayCalendarUnit | NSMonthCalendarUnit) fromDate:[NSDate date]];
/* The first public commit of Textual occured on July, 23, 2010. This is the day
that we consider the birthday of the application. */
if ([breakdownInfo month] == 7 && [breakdownInfo day] == 23) {
return [NSImage imageNamed:@"birthdayIcon"];
} else {
return [NSImage imageNamed:@"NSApplicationIcon"];
