gnome reminder

[Dimitri Mallis]

i know this is going 2 sound very stupid to a lot of people, but i
spend all my day infron of a computer & get so consumed whith what i
am doing that i forget other inportant things i should do... these are
really really basic things & this will make a lot of people laugh, but
i sometimes completely for get to eat a few meals, e.i i dont eat
lunch & supper, i just do what im doing & then get too tierd to cook
or make food. another thing i forget to do is make phone calls.

is there a program the can just be a reminder only, not bundeled up
with a e-mail client or anything like that. so that i could input
things like:

13:00 - eat lunch
15:00 - go to gym
17:00 - call billy-bob

& then it will ringe the system bell & shake the sceen untill i press
a OK button

thanks
