Is there any freely available pointcloud data? I'm especially interested in dense clouds of small areas(5m to 100m radius) but anything else would be fine too.
Tell me more

West Virginia View has some first/last files here: http://www.wvview.org/data/lidar/Gilmer/las/ This takes you through a USGS viewer, which links out to other sites (which may not have the design/interface): |

For our book "Open Source GIS: A GRASS GIS Approach" we have published a large North Carolina dataset. It contains the raw Lidar data as separated files which you can grab at http://www.grassbook.org/ncexternal/ (Lidar multi-return data). |

Ohio has LAS State wide datasets located here: |

Generate your own with a Kinect. It will provide a pointcloud with cm-scale precision for areas up to 5 m^2, and has a maximum range and FOV of about 15 m, although it is not very precise at that range. Just collect your data in the morning/evening when the sun is low, or at night. |

MD DNR has some sample LIDAR datasets available on this page, although it's already been separated out into first- and last-returns. |

Autodesk's 123D Create application can generate point clouds from photos. Just take photos of something from a few angles and then hit 'go'. I am not affiliated at all. I like it a lot, though. Very nice software. |

http://liblas.org/samples/ has a extensive sample library of somewhat interesting data, though its primary purpose is for providing examples of variability in LAS data. |
