Current techniques in microfluidic integration are limited due to external control mechanisms employed. I will review technologies for generating and manipulating drops and bubbles at kHz frequencies. I will briefly present my research on an all-fluidic, on-chip, internal flow-control scheme based on fluidic logic in microfluidic devices. I will cover some basic elements for all-fluidic computation, bubble synchronization and storage/memory. <p> In the end, I will briefly talk about a shorebird that knows more fluid mechanics than most average birds and describe some recent work on capillary ratchets. <p><p> <center> <small>Questions?
