Urs Wegmuller of Gamma Remote Sensing has made a map of uplift from differential PALSAR interferograms:
For more interferograms please see his report in pdf format.
Manabu Hashimoto (DPRI, Kyoto University) has written a very informative page about the Haiti earthquake. One of the results presented is a ScanSAR interferogram:
Falk Amelung's group at the University of Miami has made a new PALSAR interferogram:
The rupture length shown above has been inferred by preliminary modelling. We
expect to obtain better constraints on the rupture length from the
ascending interferogram expected for February 14.

Please see Eric's Haiti page for explanation.

Visible/Infrared Images
Miguel Doblas of the Spanish Research Council (CSIC) at the Museo Nacional de Ciencias Naturales of Madrid has prepared a report (pdf format) on geological deformations and hazards triggered by the Haiti earthquake.
JPL has provided two high resolution ASTER images, taken Jan 14, 2010 and Jan 18, 2009,
in GeoTIF format, co-registered, and with simulated natural color created from VNIR bands 1,2,3.
They can be downloaded from the Supersites server, along with associated world ( 2010 and 2009) files.
JPL found landslides triggered by the mainshock by comparing the ASTER images mentioned above:

Surface Deformation
DLR has prepared maps of horizontal surface displacement.
CEA has prepared maps of surface displacement components.
Anthony Sladen, Caltech has prepared a source model based on waveform inversion and used it to predict surface displacement:
Andy Freed of Purdue University has created a postseismic relaxation model:
Cumulative predicted postseismic displacements between 3 weeks and 1 year from the time of rupture based on finite element model calculations . These displacements are predicted to increase dramatically in subsequent years, though the pattern should remain fairly constant. (a) Map showing model displacements at current GPS locations (thick arrows) based on two rheological assumptions, one where postseismic relaxation is dominated by flow in the deeper mantle (red arrows in (a), red curve in b), and one where relaxation is dominated by flow in the lower crust (blue arrows (a), blue curve in (b)). The green arrows in (a) show the full pattern of predicted deformation associated with the mantle flow model. (c) and (d) show calculated vertical displacements of this time period (red: uplift, blue: subsidence) for the mantle and lower crustal flow models, respectively. (e) Shows the difference in vertical displacement between the two models
