Aww... there is hope, O ye ANU colleagues #OurANU

[Rowena Ball @[email protected] @RowenaBall]

@matthras Careful. That's three wishes. You might not have any left.

Who's a handsome brown banksia then? Proudly guarding University Avenue, these soft brush inflorescences are subtended by brown velvet bracts, just like my Auntie C's old verandah sofa. @ourANU

There is more seat leg room on a @linkairwaysau Saab 340B than on an A380, plus the turboprop engine vibrations transmitted through your seat ensure you get a free back massage!

@strom_m Mm... no, actually. Nice try by the authors though. Our results find that complexification is more of a deficit effect. In a nonequilibrium, fluctuating environment non-performing entities are inevitably broken down and 'sent' for recycling into other, possibly better-performers

Amaranthus, says my learned informant. The leaves and seeds are edible. Here it is again, proudly enjoying a bath in the longer wavelengths of the late afternoon sun

What are these extraordinary glowing crimson plumes of flowers that have appeared in the ANU community kitchen garden? @ourANU

@EverFurther Meanwhile, China smiles enigmatically...

I wondered how the train from Hull via Selby to York would actually get there. Turns out it takes this really cool sliproad - sliprail - onto the east coast main from Doncaster #trains #railways

[Rowena Ball @[email protected] @RowenaBall]

Ooh pretty posh station for a working south Yorkshire town. 175 years young, too

[Rowena Ball @[email protected] @RowenaBall]

@GarethDennis Are you at your office right now? Oh never mind - my train to Scarborough approacheth. The joys of a Britrail pass!

[Rowena Ball @[email protected] @RowenaBall]

This railway station should definitely employ a Station Cat. The position appears to be vacant

[Rowena Ball @[email protected] @RowenaBall]

@EverFurther Said with the authority of the mighty manspreader! Hope I don't have to sit next to *him* on the train

At last the tiny Shay has tracks to run on! What a weird little contraption!
Now for some wagons and switches and sidings and signals and all sorts of whatnots...

[Rowena Ball @[email protected] @RowenaBall]

A tiny brass 2-cylinder Shay is under construction. So far, just the underframe and engine. Can't wait to see it in steam!

[Rowena Ball @[email protected] @RowenaBall]

And it's in steam! Watch, just watch, sound on!
Tracks? That is a very good question. 45mm gauge needed.
