Slowly drive MATLAB users insane by doing something annoying at random intervals. Customize to deploy your own personal brand of evil.
A few ideas:
>> beep on, beep % make noise
>> disp('Why?'), why % display nonsense
>> disp(datestr(now)) % display date and time
>> calendar % display calendar
>> figure % open a figure
>> fprintf('\n') % insert blank line
>> fprintf('>') % growing prompt
>> disp('<<') % reverse prompt
>> disp('>>>') % triple prompt
>> fprintf(2, '>>\n'); % prompt in error message color
>> exit % exit Matlab (truly, truly evil)
To run this function automatically when Matlab starts, call annoyatron() from startup.m. See 'startup' in Matlab's help for more info.
