The user interface is written in Perl/Tk and was designed to be snappy even on the original Point 510 (100Mhz) tablets. I'd already replaced these tablets around the house with Point 1600 tablets (most picked up on ebay for about 50-100 pounds each) with the main advantage that the Point 1600 can run at 800x600 in full-colour rather than the 256 colours of the 510 in the same resolution.
I first looked around the web to see if there were any existing Perl/Tk projects that had exciting graphic design I could base on, but I didn't find anything very useful. In the end I decided to make the UI look like a web site design proposed by a colleague at Red Hat for some internal site that didn't get used.
The Heating interface lets you look at graphs of past readings for
any sensor or change the target temperature of the house.
Actually we only have a couple of X10 lights in the house, and
we really only ever control the living room lights.
This is just screen-scraped from the BBC website and updated
We use this screen to look at the security cameras as well
as some other Glasgow web cameras. The interface allows
multipart-jpeg streaming (compatible with ZoneMinder).
This actually displays a number of events such as the status
of the house alarm, capturing when the doorbell is pressed,
as well as popping up details of who calls us.
Old heating interface for comparison. See my original software page to see how the other screens looked.
The rest of it was just messing around with frames and alignment and creating the curved edges. I used the gimp to get a curve I was happy with, then coverted it from a GIF to xpm with reduced colours. The xpm was then coded into the application and simplified so that the program can generate the right curves for any font size.
The Perl/Tk I used to create the headings is available here and running that program displays the following:
