Happy April to all! Ay-leen lists the April steampunk shenanigans, including one in my very own hometown at the end of the month.
If you're looking for inspiration, consider the Victorian Kitchen Garden! I found this via a Metafilter post which also lists sequels, offshoots, and similar programs. There's an amazing amount there.
If you're more mechanically minded, check out the Greatest Grid exhibit at the Museum of the City of New York, or try your hand at creating a Ranque-Hilsch vortex tube. (Bonus for the latter: no one knows how it works!)
And lastly, if you're looking for a steampunky day trip and you're near Chestnut Hill, consider the Waterworks Museum in Chestnut Hill (discovered via Mike the Mad Biologist’s story of his visit). Lots of great photos and history to be found.
