This image appears on the cover of Peter Gabriel's album New Blood. It appears to be a photograph of some microscopic biological cell. But it doesn't look like a blood cell to me. What kind of cell is it?

This is an embryonic stem cell on the tip of a needle photographed on a scanning electron microscope (SEM). The image was taken by Steve Gschmeissner, see here for the original.
This looks like a macrophage to me, which is a white blood cell. Try Googling "macrophage sem" to see similar images (SEM = scanning electron microscopy/micrograph).
The clue is the nature of the cell surface - those ruffles reflect the macrophage's role in engulfing foreign material. Indeed it is possible that some of the particles on the surface are bacteria which have been opsonised and are bound by the macrophage cell surface.
In addition to Alan Boyd's answer of a macrophage, it could also be a T cell or B cell. Try doing an image search for lymphocyte SEM and browsing through the different cell types. While the traditional image of T and B cells has been of a smooth round blast cell, they actually have numerous projections, folds, etc. to aid in forming the immunological synapse.
