[nabs-l] periodic table

[programmer651 at comcast.net]

Where can I find a blind accessible periodic table for chemistry? I tried the link below, but it doesn't tell me what period/group they're in; even though it looks good visually, JAWS just reads it like a list of elements, average atomic masses and atomic numbers, but no way of indicating how they react, like it is visually.
