A few months ago I put up a post about the Bullfrog Spas Series II control panel Overlay. That control panel overlay is currently being used on all of Bullfrog’s Series II Spas. We had planned to continue using an older design for the more expensive Series I line for 2009, but the opportunity came up to redesign that panel as well. The design for the Series II control panel was well received and I was asked to redesign the Series I overlay using the same style and symbols I had used on my previous design.
