  text: At the epoch of reionization, when the high-redshift inter-galactic medium
    (IGM) is being enriched with metals, the 63.2 micron fine structure line of OI
    is pumped by the ~ 1300 AA soft UV background and introduces a spectral distortion
    in the Cosmic Microwave Background (CMB). Here we use a toy model for the spatial
    distribution of neutral oxygen, assuming metal bubbles surround dark matter halos,
    and compute the fluctuations of this distortion, and the angular power spectrum
    it imprints on the CMB. We discuss the dependence of the power spectrum on the
    velocity of the winds polluting the IGM with metals, the minimum mass of the halos
    producing these winds, and on the cosmic epoch when the OI pumping occurs. We
    find that, although the clustering signal of the CMB distortion is weak \delta
    y_{rms} ~ 10^{-7} (roughly corresponding to a temperature anisotropy of few nK),
    it may be reachable in deep integrations with high-sensitivity infrared detectors.
    Even without a detection, these instruments should be able to useful constraints
    on the heavy element enrichment history of the IGM.
