Being an engineer and a long time amateur radio operator I have always liked seeing an interesting innovation used to fix a problem, whether the fix is temporary or permanent. I've used unorthodox fixes in both my vocation and avocation over the years. It's also fun seeing how others have dealt with solving problems with only the materials they had on hand.
That being said, I found a blog devoted entirely to showing interesting jury-rigged fixes to everyday problems.
