Having seen many people viewing my website aboe, I have to add that in the last few months the theme has been "fully" responsive, with all widths, heights etc. in percentages (e.g. single NextGEN gallery images on newer posts) or EM's (e.g. font sizes and some distances between elements).
I also have tailored nextgen gallery's stylesheet in some places (e.g. imagebrowser) to use full-container wide percentages widths and min/max height limits depending on viewport/device size.
