I love doing this kind of thing.. I'm into rhythmic illusions.. i love accenting odd's when in even meters. A simple example every 3rd 16th untill it repeats (accent the > )

>e&>,2e>a,3>&a,>e&>,1e>a,2>&a,>e&>,4e>a,1>&a,>e&>,3e>a,4>&a

I've been studying tabla now from aloke dutta. There is allot of this kind of thing but times 1000. It is by far the most challenging/musical thing you can do in the percussive world. Sitting in front of a pair of tabla for the 1st time you feel like an child again..

man i was hoping to be better at ascii text tabs but i'll try to describe it best i can...
i play a basic rock beat (bass on 1 and 3, snare on 2 and 4) while playing quintuplets with my hands. right hand is on the ride cymbal and left hand on the snare. since the bass drum and accented snare (beats 2 and 4) happen every five notes like the following

R l r l r L r l r l
F

then i'll alternate my right hand between the bell of the ride cymbal and the bow (main part between the bell and the edge) for alternating sounds. this messes up my ears and lays a nice two-note pattern over the quintuplets. AND THEN i'll add my left foot tapping the hihat pedal starting on the first lowercase r above and play that every four notes. i think. at that point i can't keep track of what i'm doing so my current quest is to figure it out. i think i have it written down in standard notation. it ends up taking four measures to complete one cycle until your feet and hands line up at the beginning.
